RE: [Asterisk-Users] asterisk hardware
Hi, I have ~25 AtCom AT320 phones (PA1888S based) and they was not a good experience for me: I ran the risk to abort my Asterisk project thanks to them! I tried both with SIP and IAX2 firmware of every version but voice quality was often unacceptable. In addition, they lose often registration and became UNREACHABLE if you use 'qualify=yes'. We replaced all of them with GXP2000 and all are happy!

anyone using hardware IAX phones with asterisk ? I've googled on this issue and found several hardware phones which support IAX protocol, but before paying money I'd like to know more about what people experiencing with them. I have had three of them for neary two years. Here's an executive review: They're dirt cheap You get what you pay for. Some (not all) firmware has clicks and hums. The later phones look and sound better and are more robust. You can get the firmware and tweak it (see yahoo group) Many languages are available since users have the firmware They do both SIP and IAX, (one at a time via firmware change) They will speak the ip address, server address etc, good for unsighted users. Many don't like this and have disabled it (by a firmware tweak) Conclusion: these phones are excellent for use on the road (assuming a real Internet connection and not through a proxy as many hotels do). I wouldn't recommend them for daily intensive use as they aren't built for it. All of my phones have been continuosly online and working for over one year. They are perfect for setting up asterisk, tinkering with firmware and settings, giving a phone to distant firends or relatives.

Re: [Asterisk-Users] asterisk hardware
Well, to tell the truth, the phones, what available in Hungary, is 90% working. The other 10% is sometimes bad as you get out off the box, sometimes it's noisy, echoing, crappy sound, rebooting, etc. Is i asked so many folks on Cebit (who resells this phone) most of them, told me, there are two kind of this phone. One is cheap and crappy, other is not as cheap but at least working :-) Either way, i think the chip itself is working nice, has gpl source (look on voip-info.org) so you can go for it, and don't undertake the chip because of a nasty manufacturer.

RE: [Asterisk-Users] Asterisk hardware for new office suggestion
Hi, We setup a HP DL360G2 (Xeon 2.8*2, 2G RAM)server Digium TE110P (E1 PRI to telco) for a small office. Include 70 IPF-3000 phone in office 10 phones on another warehouse. Between the office and warehouse we use the G.SHDSL in bridege mode to connect each other. I suggest you can setup a small lab to test the autoprovision on the phone. Include the config file and firmware upgrade. E.g, The ipf-3000 can download the config files new firmare from the tftp server. But this phone always waiting user to press '1' for upgrade new firmware. It's to hard to upgarde 80 phones. So only 1 model phone for office and test the autoprovision functions.

QoS on the switch in a small office is not likely to do anything useful. It may help some on the firewall, but it really only impacts outbound packets, not inbound. A rather inexpensive way around all that is to simply implement a second dsl link used only for voip. The size of the * box is more oriented around number of simultaneous calls and other apps running on the box. E.g., if the 30 employees never place a call, a 600 mhz processor will be just fine. ;) As I recall (which leaves accuracy questionable), several people have implemented a basic * system on old 600 mhz boxes. However, a call center with lots of call recording functions (etc) and high call volumes may require the largest/fastest processor money can buy. There is no magic list comparing sip phone quality, features, etc. Lots of reasonably good comments on the wiki, but that's about it. Lots of opinions, but keep in mind that what one person with soho-only experience considers good is highly likely to be rated poor by someone that supports a large corporate environment. Interpretations of quality varies dramatically based on each person's experience level. An individual in a less developed country might consider a softphone on a PC high quality (compared to their existing telephony infrastructure), but another person in a more well developed country would not use a softphone in production if their life depended on it. For sip phones, I'd suggest starting with identifying some basic requirements and go from there. For example, if you don't want to do any additional cat5 cabling, using a phone with two rj45's (internal ethernet switch) might be a requirement. Is speakerphone capability needed? How many extensions are truly needed at each desk? Is intercom paging required (to individual sip phones)? Is the key system emulation of a busy lamp field required? Is PoE truly required? If the answer to just those questions are a mandatory yes, you've just eliminated about 80% of the sip phones on the market. I'd expect you to find a need for two or three different types of phones somewhat oriented around high-quality (exec types), medium (average office worker), and lower quality (break rooms or occasional user). And, don't overlook the differences between key systems and pbx's. If your customer is accustomed to an existing key system, they are likely to be very disappointed with a pbx unless you spend a fair amount of time up front educating the employees and managing expectations (way before deployment). ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

We will have 8 channels (still not sure if 4xISDN2 or ISDN30 8 channels, but I will definitely go for a Digium card with echo hw cancelation) and a DSL 2mbit line (QoS on the switch and firewall?), to be configured for both traditional and VoIP usage .

Thanks, any hint really appreciated Simone I can only base my advice on what we have done for a smaller office. If you want 8 lines it is probably as cheap to go for ISDN 30 as for 4xBRI at least it is here in the UK. We have a single span E1 card from digium without echo can in a small 1U rack mounted server (spec: 1Ghz Via processor and 512Mb ram). The Via might be a bit underpowered for 30 users, but unless you are transcoding, virtually any modern processor would be fine for 8 lines. You need to look out on the DSL line if it is ADSL, since they have low upstream bandwidth. Heavy outgoing mail messages (eg attachments sent to distribution lists) can easily fill the outgoing (256kbit/s) pipe degrading the voice quality. I'm very fond of the SNOM phones - elmeg are selling the old SNOM 190 model which is a decent office phone. For 30 you should be able to get them for less than £70 each. I've got 6 - 4 SNOMs and 2 elmegs - No problems with any of them, but they don't support PoE, so you may want to look at other models. Don't underestimate how much training/doc you will need to provide to get people going on the new system. They may have been using the old one for years and written little cribsheets about how to transfer etc. Tim Panton [EMAIL PROTECTED] ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Fabrice a écrit : Hello all, Just a question, on asterisk box : I looking on the web , for asterisk at large , and 'asterisk future of telephonie' ... If we would like to change our OLD PABX 600 phone with 4 E1, to install a asterisk with full ip phone in SIP, Could we use 1 Box for asterisk with voicemail, zap channels and some agi script ? Short answer: yes. Long answer. If I had to do something like this, I would: 1) Buy a big box (the one I just bought is a dell 1850 with redundant power supply, raid1 disks, etc) - see dell.com 2) Grab a digium card: http://www.voipsupply.com/product_info.php?products_id=913 3) Buy some decent SIP phones: http://www.voipsupply.com/product_info.php?products_id=758 (I haven't tried those yet but they have a good reputation) As for the Asterisk distro I really like Xorcom Rapid: http://www.xorcom.com/ It's debian based, it's clean, and I'm sure the author won't mind you hiring him to get the 4E1 card working and configure the distro to your liking. Once it's done, save the disk image (using dd, or mindi / mondo) to make sure you can redeploy quickly in case of emergency... All in all you're probably looking at €15-20k for a typical PBX replacement. You probably want to look into VoIP as well to reduce operational costs... Old PSTN providers are expensive, with some IP routing (at least for some of the outbound calls) you can probably recoup the investment over a few years thanks to phone savings.

Yes, transcoding is not going to work for that density. asterisk doesn't do g723, and even if it would your system would not be able to handle more than 150 simultaneous g711 to g729/g723 transcodings.

Re: [Asterisk-Users] Asterisk Hardware recomendation
How would one go about to implement such a cluster? How do the different Asterisk boxes know of the extensions on all the other boxes? Is each client bound to it's box or can it connect to any box in the cluster, ie if one fails can the other take over and share the load of the failed on between themselves? I would be very interested in hearing more of such solutions and people experiences with it.

Re: [Asterisk-Users] Asterisk Hardware Architecture Group
Sounds like a wonderful idea! I can tell you from personal experience that the performance of Asterisk and its stability are in a one-to-one relation to the hardware that you're using. We've been using mostly Intel boards for Asterisk, mainly the ClearWater (XEON) and TorryPine (P4) boards for Asterisk, and they always proved the most reliable. We are now working on finalizing our Asterisk based appliance box, which is based on a TYAN board, and I have to admit that it exhibits the same behaviour as the TorryPine, with some advantages in terms of user experience for configuration of IRQ's and MB resources. I have resources for forming such a group, shall we all proceed ?

RE: [Asterisk-Users] Asterisk Hardware Recommendation
If price would truly not an option just get one of the Signate Telephony 5000 servers(http://www.signate.com/pbx.php) They are about $18,000 and allow you to have upto 5000 SIP streams go through it. You could have that be your gateway and do the SIP-IAX through that machine and scale upto 100 T1s if you want. But that is a bit steep. So on to your choices. I would really say that the setup you choose will depend on what kind of users you have as well as how often you need to change/add users to the system and how the users are using the system at what times. Any of them that you listed could work depending on how they are used, but in some cases you may not want to use some of the scenarios listed because they would either be incapable of meeting your needs or overly complex to manage. The easiest and cheapest one would actually not be listed: Scenario 6: Direct SIP-Zap on two separate servers half SIP users on each server PSTN --2xT1-- A1 SIP_Agents PSTN --2xT1-- A2 SIP_Agents There is really no reason to have another 2 servers running IAX to the T1 servers, and this is simple and easy to set up and involves only 2 machines. The next setup I would recommend would be Scenario 4, although you will have to get a machine with a fast/wide BUS(like an Apple G5) to handle ever increasing numbers of SIP-IAX streams as the system would grow. If you can explain more about what kind of use this system will have I can give a better recommendation.

I have the following questions based on a hypothetical scenario and some assumptions: Based on the price of these configurations, I wouldn't even mind putting two servers each with 2 T1s just so that I could get all calls recorded and distribute the risk of failure. Now, I don't know if it would make a difference or not, but here it goes: Assuming the cost of the systems is of no importance for a moment (actually looking for the most scalable and reliable solution), which would be a better approach to solve the issue of activating 4 T1s which will be constantly taxed with load and be able to record all conversations: Scenario 1: 4 T1s into Asterisk (A1) where all SIP agents register. Call recording in A1. PSTN --4xT1-- A1 SIP_Agents Scenario 2: 4 T1s into Asterisk (A1) to do TDM-IAX transcoding. Asterisk (A1) connects to Asterisk (A2) via IAX where all SIP agents register (IAX to SIP transcoding). Call recording in A1 or A2. PSTN --4xT1-- A1 A2 SIP_Agents Scenario 3: 4 T1s into Asterisk (A1) to do TDM-IAX transcoding. Asterisk (A1) connects to Asterisk (A2) via IAX where half of SIP agents register to, and the other half would register in A1. Call recording in A1 and/or A2. PSTN --4xT1-- A1 SIP_Agents A1 --IAX-- A2 SIP_Agents Scenario 4: 2 T1s into each Asterisk (A1 and A3) to do TDM-IAX transcoding. Asterisk (A2) will connect to A1 and A3 via IAX. All SIP Agents register at A2 (IAX to SIP transcoding). Call recording in [A1 and A3] or A2. PSTN --2xT1-- A1 A2 SIP_Agents PSTN --2xT1-- A3 A2 SIP_Agents Scenario 5: 2 T1s into each Asterisk (A1 and A3) to do TDM-IAX transcoding. Asterisks (A2 and A4) will connect to A1 and A3 respectively via IAX. Half SIP Agents register in A2 and other half in A4 (IAX to SIP transcoding). Call recording in [A1 and A3] or [A2 and A4]. PSTN --2xT1-- A1 A2 SIP_Agents PSTN --2xT1-- A3 A4 SIP_Agents Hopefully you're all able to understand my 5 scenarios. I guess, my questions would be: 1) Is there a load limiting factor in terms of whether you do the Monitoring of the calls when you're doing TDM-IAX transcoding or IAX-SIP transcoding? 2) Will a single CPU machine handle the 4 T1s to do TDM-IAX transcoding, if another machine is doing the actual recording (IAX-SIP transconding) (Scenarios 2,3,4,5). Basically, just setup cheap Asterisk boxes to act as VoIP gateways and the distribute the load and/or intelligence on other Asterisk boxes to connect SIP agents and all dialing rules, etc?

For that you can have a system for about $1500-$2000 that will be able to fully record 2 T1s(48 channels) worth of Zap-SIP conversations. Putting two of those together with a nice big fileserver will give you a lot of flexibility, as well as only a reduction in capacity if one of the servers go down instead of a total outage, for about the same overall price of a single high-end Dual Xeon server.

Re: [Asterisk-Users] Asterisk Hardware Recommendation
Sure. I setup a small lab on a machine with 4 T1s and 36 agents logged in. The system was configured to Monitor all outbound calls as well as monitor all calls distributed by Queue app (monitor-format setting in queues.conf). When recording to local disk, everything was working fine. Agents were busy 99.5% and there were at least 30 calls waiting in Queue to be distributed. Average call conversation length was about 7.5 minutes. Then I mounted /var/spool/asterisk/monitor via NFS using 10/100 Fast-E. The moment we pushed the load on the Asterisk machine, everything worked for about 40 seconds. Then call quality started suffering significantly. Chopped audio. Bad audio. No audio. Good audio. You could imagine. So we stopped the test. Then we unmounted the NFS drive and repeated the test again. Everything worked fine again. The machine we tested asterisk on is a dual Xeon 3 GHz with 2G RAM. During all tests, CPU utilization was about 55% on the average (for each CPU). Memory usage was under 1G. I would say I need to try more troubleshooting. Maybe there was congestion on the Fast-E, although preliminary analysis indicates there were no CRC errors, collisions, or packet loss. The NFS machine was completely idle. Last, we repeated the test over a 1 hour period. This time, Monitor was recording on local drives and we were copying files every 15 minutes with a background process (perl script) to NFS mount point. Everything worked fine as well. I don't know if these tests are conclusive yet. However, from the results so far, I would recommend staying away from recording to NFS mounted point. I will continue running simulations to see if anything else can be identified.

Re: [Asterisk-Users] Asterisk Hardware Recommendation
Well, I don't think I'm ready to spend that much money :) I understand your point regarding that load depends on usage. SIP_Agents are simply agents answering calls. Average call length would be about 8 minutes. During some of these calls (maybe 25%), agents will conference the call (PSTN channel) with internal IVR script. I like Scenario 6. Will look into that further. However, if the above information gives you more grounds to make additional comments, please do so :) Thanks, Daniel On Apr 29, 2005, at 10:21 AM, mattf wrote: If price would truly not an option just get one of the Signate Telephony 5000 servers(http://www.signate.com/pbx.php) They are about $18,000 and allow you to have upto 5000 SIP streams go through it.

Thanks Daniel, We may end up replicating your tests in order to confirm some of your results. I don't know if it will be anytime soon, because we don't have the hardware yet. Regardless, I will share my results with the list. Anyone out there have any ideas on why the NFS mount affected call quality?

Hi Matt, Does anyone have experience with using NAS (http://en.wikipedia.org/wiki/Network-attached_storage) or SAN (http://en.wikipedia.org/wiki/Storage_area_network) for this application? I've had our agent/queue recordings dumped both to local disk and SAN (currently using local disk as the SAN is being used for some other stuff). With both SAN (2GB FC) and local disk, we haven't had any problems like the ones described by Daniel. One of our live servers has 4 PRI's going with an average of about 40-50 calls at any given time during the day (60-70 peak), all being recorded, and we've had zero issues. The other two servers have similar configurations, but lower call volumes (5-20 calls depending on time of day). I'd be leary about doing it over NFS or Samba or any other sort of networked filesystem though. For our servers, that'd be extra I/O that'd have to go over either one of the network interfaces (both of which are plenty busy already with IAX2 and/or SIP). I guess it depends on your network card and how well behaved it is in terms of interrupts/etc.. You could say the same thing for local disk if you had slower drives and/or disk controllers.

However, I base my purchasing decisions on quality of equipment and service, and their price is certainly what I consider inexpensive when I balance it against those two other criteria. Sometimes they're a bit slow on shipping, as they build a lot of their gear to order, but I can typically wait a week or so. I've ordered probably 30 or 40 systems from them in varying configurations, and I've not had a return yet. I don't know if they actually ship anything other than SuperMicro motherboards, but I'd suggest specifying them in your order. I've had very good luck with those MB's in my Asterisk platforms. Plus, their on-line pricing and configuration tool really makes things easy to get a price quote without dealing with salespeople (not that their salespeople are bad, but it's just time-consuming trying to get someone on the phone.) This thread should probably move over to asterisk-biz if it's going to be extended...

RE: [Asterisk-Users] Asterisk Hardware Recommendation
I have never been able to do more than 50 concurrent recordings with Zap - SIP phone calls without the audio skipping and/or breaking up. Also, if you are using Digium TE4XXP and want to do a lot of recording I would recommend against a SCSI RAID card because of the interrupt conflicts that you will run into over time. I would recommend a couple of cheaper Asterisk servers with a dual T1 or Quad T1 board in them and SATA drives, with a nice big archive server that the audio will be copied to several times a day. Also, do not record(Monitor) with the 'm' flag on because this will also lead to more disk read-write while you are already trying to write another 100 or so streams. Offload the -in and -out files to the archive server and let it soxmix them together instead. This is the method that we have settled on for our 12 Asterisk servers and it works rather well for us.

Re: [Asterisk-Users] Asterisk Hardware Recommendation
Daniel, Could you expand upon your experience recording to an NFS mounted drive. We are looking to use a TDM-VoIP gateway to route 16+ spans to a single Asterisk server. We were hoping to Monitor using the following scheme: - Monitor application executed on Asterisk server (no 'm' flag) - Pick a codec that the Monitor application can record in natively so that no transcoding is done on the leg files (can this be done?) - Record the leg files to an NFS mounted drive on a remote machine - Have soxmix take care of mixing and transcoding the leg files into the desired format on the remote machine According to you this now looks like a VERY BAD IDEA. Does anyone out there have any experience using monitor to digitally record large numbers of spans (16+) on a single Asterisk server using a VoIP gateway instead of TDM cards? Is it feasible? We are trying to keep the Asterisk server as slim as possible, but would like to stick to one box so that we can have centralized queuing, configuration, and reporting. Has anyone had any luck using Monitor to record to an NFS mounted drive? Are there any other options to remove the overhead of the disk subsystem when recording calls?

RE: [Asterisk-Users] Asterisk Hardware Recommendation
You can throw together a single P4 3GHz with 1GB RAM and 2 x 80GB SATA HD for about $600. One of those can easily handle a Sangoma dual T1 card($900) or a Digium quad T1 card($1400). For that you can have a system for about $1500-$2000 that will be able to fully record 2 T1s(48 channels) worth of Zap-SIP conversations. Putting two of those together with a nice big fileserver will give you a lot of flexibility, as well as only a reduction in capacity if one of the servers go down instead of a total outage, for about the same overall price of a single high-end Dual Xeon server. Building your system this way from the start will also allow it to scale much more easily than using just a single very expensive server. You can just add another 2 T1s of capacity at any time for just $1500. I recommend only 50 or less recordings concurrently because that is the ceiling that we discovered while trying Zap-SIP recording on both Dual Processor server-class systems and single processor cheaper commodity computers as well as on SCSI, IDE and SATA drives.

Re: [Asterisk-Users] Asterisk Hardware Recommendation
This is great information. I have the following questions based on a hypothetical scenario and some assumptions: Based on the price of these configurations, I wouldn't even mind putting two servers each with 2 T1s just so that I could get all calls recorded and distribute the risk of failure. Now, I don't know if it would make a difference or not, but here it goes: Assuming the cost of the systems is of no importance for a moment (actually looking for the most scalable and reliable solution), which would be a better approach to solve the issue of activating 4 T1s which will be constantly taxed with load and be able to record all conversations: Scenario 1: 4 T1s into Asterisk (A1) where all SIP agents register. Call recording in A1. PSTN --4xT1-- A1 SIP_Agents Scenario 2: 4 T1s into Asterisk (A1) to do TDM-IAX transcoding. Asterisk (A1) connects to Asterisk (A2) via IAX where all SIP agents register (IAX to SIP transcoding). Call recording in A1 or A2. PSTN --4xT1-- A1 A2 SIP_Agents Scenario 3: 4 T1s into Asterisk (A1) to do TDM-IAX transcoding. Asterisk (A1) connects to Asterisk (A2) via IAX where half of SIP agents register to, and the other half would register in A1. Call recording in A1 and/or A2. PSTN --4xT1-- A1 SIP_Agents A1 --IAX-- A2 SIP_Agents Scenario 4: 2 T1s into each Asterisk (A1 and A3) to do TDM-IAX transcoding. Asterisk (A2) will connect to A1 and A3 via IAX. All SIP Agents register at A2 (IAX to SIP transcoding). Call recording in [A1 and A3] or A2. PSTN --2xT1-- A1 A2 SIP_Agents PSTN --2xT1-- A3 A2 SIP_Agents Scenario 5: 2 T1s into each Asterisk (A1 and A3) to do TDM-IAX transcoding. Asterisks (A2 and A4) will connect to A1 and A3 respectively via IAX. Half SIP Agents register in A2 and other half in A4 (IAX to SIP transcoding). Call recording in [A1 and A3] or [A2 and A4]. PSTN --2xT1-- A1 A2 SIP_Agents PSTN --2xT1-- A3 A4 SIP_Agents Hopefully you're all able to understand my 5 scenarios. I guess, my questions would be: 1) Is there a load limiting factor in terms of whether you do the Monitoring of the calls when you're doing TDM-IAX transcoding or IAX-SIP transcoding? 2) Will a single CPU machine handle the 4 T1s to do TDM-IAX transcoding, if another machine is doing the actual recording (IAX-SIP transconding) (Scenarios 2,3,4,5). Basically, just setup cheap Asterisk boxes to act as VoIP gateways and the distribute the load and/or intelligence on other Asterisk boxes to connect SIP agents and all dialing rules, etc?

Re: [Asterisk-Users] Asterisk Hardware
Does some hardware just not work very well with Asterisk? Yes. (or, no, depending on how you view the question) I've got a fresh installation on a Fedora C2, P4x2, 2GB Ram. Some people have reported problems with FC3, I don't know if FC2 is the same... While listening to the demo over a softphone (over the LAN) I get a number of crackles and skips. IS THIS NORMAL FOR ASTERISK? No. Or is it hardware related? It may well be software related - try a real SIP phone instead of a softphone and see if the problems persist. Softphones are not as good as hardware SIP phones. Or, find the option in your softphone that relates to transmit silence and turn it off.

I'm using the X-Lite soft phone, it has these codecs selected G711u G711a GSM, iLBC SPX. I'm not sure which one it ends up using though. You can see which one by looking at the codecs above the dial during a connection. I played with turning off all but GSM, and it didnt seem to make a noticeable difference. X-Lite needs to have silence suppression turned off (as someone already noted): Advanced system settings - Audio Settings - Silence settings - Transmit Silence: YES Other than your sound card or codecs, (try ULAW) asterisk should sound fine with X-Lite or any other software phone. ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Right? Ideally, you probably don't want to have more than 2 (and at the max 3) of the TDM cards in your system. Each of the TDM cards should have it's own interrupt in your system. With (on most PCI buses) only 4 interrupts available to the PCI bus, it's extremely difficult to get 4 cards working well on a single system. and what is the Asterisk support for Digital phones? SIP, H.323, MGCP, and (of course) IAX :-) (you can find more info about all this on the various websites http://www.asterisk.org, http://www.voip-info.org/). I prefer SIP or IAX :-). The rest are a little bit more interesting to set up.

I am usually a friend of open source software and read about the Asterisk poject, but I can not assess if Asterisk fulfills all our requirements. It would be great to receive some input from experienced users to be able to convince our management. My question is if the following scenario is possible with Asterisk and the estimated cost for it: HARDWARE - 1 external PRI E1 S2M 30 channel ISDN line - 1 internal PRI E1 S2M 30 channel ISDN line (for IVR test server) te410p can do both. (around 1500US$ for 4 E1's on one card which cn be internal external whatever) - 8 internal BRI S0 regular 2 channel ISDN lines (for smaller IVR test servers) OctoBRI for www.junghanns.net (around 1.1k EUR) - 8 internal analog lines (for DECT phones and fax) 2 tdm40b (around 400$ each) - 40 internal VoIP phones (Grandstream Budgetone?) sure, cost depends on phones. Personally I would rather go with 3 octobri's and use isdn phones :) SOFTWARE/FUNCTIONALITY - direct call through to phones with extension from external yes - voice mail yes - using VoIP softphone for home office days (and re-routing extension to it) yes - CTI support (dialing from within Outlook using hardware VoIP phones) there is a project for that which sems to work although we havem't tested it yet - UMS support (storage of voice and fax on harddisk and possibility to mail it around) check out the fax channel from steve underwood, it should do what you need. Is this possible with Asterisk and can you indicate the cost for such an environment ? thanx a lot!
