Re: [asterisk-users] IAXModem or T38Modem?
Hi, I'm installing Hylafax on my Asterisk system. From what I've read, I can either use IAXModem or T38Modem to provide the virtual fax device. we are using T38modem, it was a long way to get it stable, but finally it works quite good with 10 parallel running T38modems. But your carrier has to support T38, when we began to evaluate this some years ago, this was not true for all. -- kind regards, T. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

[asterisk-users] High Availability with Asterisk
Hi everybody, what are the current options to get an Asterisk-system high available? Using two servers as active/passive with DRBD, Pacemaker/Corosync works very good, there are no quality issues of the voice quality, even not on high loaded servers and no problems with a lot of small packages. But for this you need two systems for every Asterisk-system, what is not economic in any way. Using (para-)virtualization with Xen could be an other option, on systems with low load this works reliable, but what happens on systems with high load? Are there any issues known about problems with the realtime, packet loss etc. because it runs in a VM? The idea would be having a HA-cluster of two servers with Xen, each of them runs one instance of an Asterisk-system in a single VM and on a failure the VM will be restarted on the other node. This might result in a much higher load on this node, because is runs two VMs, but for a short period, until the other node comes back again, it might be tolerable. Are there other options running two Asterisk-instances parallel on one system, each binded on it's own IP, maybe s.th. with chroot or similar?

Re: [asterisk-users] FAX Issues
Hi, In my office I have 1000 ext, each users has it's own DID number. What I would like is that each user can get a fax using his own number. I'm fighting with this since some time too. My experience is, that faxing over IAXModem is not reliable. So I'm going with T38Modem, my provider also supports T38 and finally I got Mail-2-Fax with T38Modem, HylaFax and Asterisk 1.4 runnig. I still have some issues with Fax-2-Mail, I had to patch T38Modem to get it working with Asterisk and it only works with Asterisk 1.8. But anyway I think it's better using T38Modem with T38 fax, than using IAXModem that uses G711 and which often makes problems with sending faxes. -- Chau y hasta luego, Thorolf -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] Multiple Asterisk Sessions on same machine
Hi, so is it possible to install a separate instance of Asterisk on the same machine (without using Vmware or such) and set the 2nd instance to listen on another port? you might try it with Xen as virtualisation solution, because especially when using it with Linux as paravirtualised guest, it has very little overhead. Depending on the number of accounts and calls you might run into issues with latency and so on, but on a small environement with two Xen guest instances, each with one Asterisk, it runs quite good. KVM also might work, but I have no experience with that. -- Chau y hasta luego, Thorolf -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

[asterisk-users] Fax with Asterisk and T38Modem
Hi, I'm fighting with HylaFAX, Asterisk and T38Modem since some time, to get fax2mail and mail2fax working, my SIP-provider only supports T38 and thus using G711 with IAXModem is not an option. I have got running mail2fax with HylaFAX+ 5.5.0, Asterisk 1.4.20 and T38Modem 2.0.0 successfull, but I'm not able to upgrade to anything newer than Asterisk 1.4.24. I was able to break down this problem to some changes in the chan_sip.c, where a improved support for T38 on initial INVITE has been implemented (see: https://reviewboard.asterisk.org/r/208/diff/#index_header). I'm not sure what the problem is, but it seems that the T38 handshake does not work correct any more. Goal is, to get running this with the latest Asterisk, right now 1.8.4.3, Is there s.b. who can give me a hint how to solve the problem? For fax2mail I use Asterisk 1.8.4.3, but it is not working too, after a fax call, the connection with T38Modem is established, HylaFAX reports ANSWER: FAX CONNECTION DEVICE '/dev/ttyT380', but a fax is never received. In the tcpdump I see the correct handshaking between Asterisk and T38Modem, but finaly T38Modem switches to recvonly and Asterisk answers with SIP/2.0 488 Not acceptable here and the call ends shortly after that. Probably there is a problem in T38Modem, so I filed a bug at sourceforge for that: https://sourceforge.net/tracker/?func=detailaid=3337581group_id=152230atid=783657 But may be, somebody has a solution for this too.

[asterisk-users] ISDN-FAX with Asterisk
Hi everybody, since some time I am looking for a current and reliable solution to send and receive faxes (probably fax-2-mail and mail-2-fax) in conjunction with Asterisk. For testing I am using a HFC-ISDN passive PCI-card, in production a Digium Dual T1/E1 PCI-card will be used. I run CentOS 5.5 (Kernel 2.6.18) and Asterisk 1.4 (but I also can use 1.8) but did not find any solution where I think that's it. What are you using? mISDN, CAPI4linux, HylaFAX, IAXmodem, chan_misdn, ... ? Can you point me to the correct direction, may be there are some more or less current howto's (more current than the ones from 2007 and earlier you find everywhere in the net)?

Re: [asterisk-users] Which virtualization tech to get PCI assignment ?
Hi, I'm looking for a virtualization technique with which I could easily assign PCI/PCIe boards to virtual machines. you might try opensource Xen with paravirtualized Linux-guests, which supports PCI-passthrough quite good. Running several Asterisk-servers at one time might be problematic, because of real time and latency problems, but using just one system should be possible. -- Chau y hasta luego, Thorolf -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] How to create a coredump for Asterisk
Hi Luki an all others who answered, Try kill -6 (i.e. SIGABRT). That usually triggers a core dump for me. yes, that works for testing and creates a coredump. Thank you very much for your answer! PS: Running Asterisk under GDB unfortunately is not an option, because it is a production system and it only crashes very, very seldom. Normaly it works for months without problems, but once Asterisk crashed 3 times a day. Now the system works stable since some weeks again and we have no clue why it crashed. -- Chau y hasta luego, Thorolf -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

[asterisk-users] How to create a coredump for Asterisk
Hi everybody, sometimes we have an Asterisk-crash, but no clue why this is happening, so I'm trying to make a coredump to analyse it. I compiled Asterisk 1.4.20.1 on CentOS 5.4 i386 with DEBUG_THREADS and DONT_OPTIMIZE, then I start it with: # /bin/bash /usr/sbin/safe_asterisk This should do an ulimit -c unlimited, but I entered it in the terminal again. A # ps -ef | grep asterisk tells me that Asterisk is running as root and with the g-option for writing a coredump: root 21622 1 0 20:15 pts/000:00:00 /bin/bash /usr/sbin/safe_asterisk root 21627 21622 1 20:15 pts/000:00:00 /usr/sbin/asterisk -f -vvvg -c In the asterisk-start-script, the coredump-dir is configured as: DUMPDROP=/tmp Unfortunately, if I kill all asterisk-processes with kill -9 ..., a coredump never is writen to /tmp, I also looked in other dirs. Any idea what is going wrong here?

[asterisk-users] Mail-2-Fax and Fax-2-Mail solution for Asterisk with T38
Hi, I am looking for an Mail-2-Fax and in a second step Fax-2-Mail-solution that works via T38 with Asterisk, currently still version 1.4 but it also should work with 1.6. For Mail-2-Fax I am thinking that you either have to install a special printer-driver on your Windows-PC (Mac and Linux would be good too), where you can print your fax too and where you have to enter the destination number. Second possibility would be, that the user sends an e-mail with the attached fax to the server, the server has to open the attachment, converts it and sends it via T38 to the number found in the e-mail-body. I would prefer if the attachment would be an image or pdf only, but it also might be nessecary to support office-formats too. The Fax-2-Mail-solution might be more simple, the system receives the T38-fax, converts it in TIF, JPG or PDF and send it via E-Mail to the person that is assigned wit the fax-number. I would prefer a Linux-based opensource-solution, but if there are other good solution I might look at them too!

Re: [asterisk-users] Wi-Fi sip phones with auto provisioning
Hi, Im looking for wifi sip phones that support auto provisioning and work flawlessly with atserisk. Can anyone suggest me some models? I have not yet tested it with provisioning because right now the provisioning server does not support this model. But I use a Snom 820 and 870 with an extra USB-Wifi-stick (ALLNET ALL0233RP 300MBit) instead of ethernet and this works quite good. Unfortunately I do not like the 870 at all, bad quality, bad user-interface (touch screen), for me the 820 is better to use.

[asterisk-users] Source-IP on Asterisk DRBD/-HA-Cluster wrong
Hi all, I installed a Linux-HA-cluster with DRBD and Asterisk 1.4 on it. Actually it might work quite good, failover etc. works, even if this is not a 0-downtime solution, because current calls are dropped and the phones not are reachable until they reregister at the Asterisk. It might work good, because my phones are not able to register at the cluster-ip address, because the REGISTER arrives at the cluster-ip, while Asterisk responds from the real host-ip of the active cluster-node. The registration with the real ip works, but then I can't use any failover solution. I have already checked several solutions found at http://www.voip-info.org/wiki/view/Asterisk+High+Availability+Solutions and some others returned by searching the net, but nothing that helped me out. I see three possible solutions: - is there a parameter in Asterisk to set the source-ip? - patching Asterisk to include such a parameter? - would be changing the primary ip-address to the cluster-ip and changing the real host-ip to an alias, a good solution?

[asterisk-users] Asterisk build-environment in Xen-DomU
Hi, I'm trying to migrate a Asterisk build-environment from a physical to a paravirtualized machine on Xen 3.0 - on this system Asterisk don't need to run at all, it is only for building RPMs. Host OS and guest OS both are CentOS 5.2. The build of Asterisk, Asterisk-addons and Zaptel works, but MeetMe and some other components are not compiled because Zaptel was not installed on the system. It seems not to be possible to install zaptel in a Xen-PV because of the lack of a RTC, so first try was to remove every thing RTC-related in zaptel-1.4.11 but I had no success with that. So I adapted the ztxen-1.4.2-patch to zaptel-1.4.11 and compiled it successfully. I installed asterisk-1.4.20.1, asterisk-addons-1.4.7 and zaptel-1.4.11 on my PV-system and adjusted the zaptel.conf that it only loads the ztxen. lsmod tells me that the module is loaded: Module Size Used by ztxen 7840 0 zaptel190852 1 ztxen crc_ccitt 6337 1 zaptel But make menuconfig - 1. Applications still has XXX 32. app_meetme which means that that zaptel is missing. If I compile anyway the module apps/app_meetme.so is not created. Any idea how I can resolve this problem?
