Hello *, I have the Pirelli phone (there are two actually, I have the bar-type one, I think it's L10) in daily use, both GSM (O2 Germany) and WLAN (registered to Asterisk of course - behind OpenWRT boxes, FritzBoxes, D-Link APs whatever is there). I had the latest firmware in August, did not check back since. In my opinion, this phone is not ready for production use for regular users. It works really nice in the short run, but a few things make it unacceptable or at least lack for my approval as a "well-done product": - Connection loss on DHCP expiry (twice yet) - Relatively poor Wifi signal strength, compared to other Wifi devices - frequent lockups, which require battery removal and clock reprogramming: - if you power on the phone while it is on charger power - if you receive a WIFI call while you have a WLAN call, and the WIFI call is from the same "contact" in the phone book - plugging in, unplugging, plugging in headset fast in a row - no SIP voicemail support, GSM voicebox only (pressing "1") - slow user interface It further lacks - one-touch silent mode - you can only kind of emulate that - proper headset support - "any key accept call" does _not_ work, although it is a separate choice from "accept key accept call". Auto-accept works OK though. Vibra seems to _not_ work once a headset is plugged in... or at least not always. - one-digit press in main menu to open the menu: It works in the submenues, but you always need to navigate the main menu with the arrow controls - quick mode switch WLAN on/off - if you are out of home range, WLAN seems to suck lots of battery. - display of CALLERID(name), currently only CALLERID(num) is displayed I would also like a modus which is "if no known network is in range, connect to any unencrypted network you can get that seems to have network connectivity". This should of course be optional. That said, for my personal uses it is OK, lightyears in front of the two UTStarcom phones I also had in daily use. Well, while they worked anyway. Both the good WPA support (basically broken in the UTS) and the GSM function make me like it. The phone book (multiple entries) is great, although it would be nice to see from which of the numbers listed the call is coming (call Sam back on his mobile, or is he at home?) I believe most of the problems I see could be solved in software quite easily, but until they are, I would not give it to my users, rather I would go with DECT, Siemens Gigaset ISDN, on FritzBoxen internal S0 bus, because this combination I know works absolutely perfect, as good as ISDN, and that means a lot. I have been using the Pirelli for five or six months, and keep using it because the GSM/WLAN combo is just the killer app on it. It sucks a bit more than my regular mobile phone (which I sometimes carry instead, I have a Dual-SIM contract), but for me all mobiles suck. I have thin fingers, but using mobile keypads always makes me feel like having jelly sticks on my hands. That is why I love the BudgeTone 100 phone :-P Best regards, Anselm P.S.: "Your fingers are too fat to dial - please mash the keys for your free dialing wand" -- phone announcement in Simpsons "King Size Homer" ___ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Re: [asterisk-users] Recommendations for 100 Wifi SIP phone setup
I would like to share some facts about wifi and wifi security vis-a-vis wifi phones. First off, it takes REAL time to negotiate the 4-way-handshake. Not even thinking about the 802.1X authentication. Thus a person walking at a normal rate, going through a door will find themselves disconnected from the AP on the one side of the door and trying to connect to the AP on the other side. This can result in a lose of connectivity exceeding the ITU's 50ms max outage time (cellular systems have aways targeted 35ms). This is part of the reason why I added PSKSA caching to the standard (yeah, the whole SA nomenclature was my doing, lifting it from my IPsec work). The problem is moving the PSKSA cache around the APs. 802.11F was rejected by the vendors as a solution (and I did the security on that). Thus was born thin APs with the security SAs held back in the switch and work on the 802.11r addendum (and is that ever a kitchen sink). So if you want more than WEP, you NEED one of the thin AP solutions for mobile devices like phones. Also you need some good processing power and code space (boy did the Spectralink engineer scream). So, yeah, real wireless security is a real problem on handhelds. Of course, in the end we will need 802.11s for real moblity in a large area. Oh, and security with DECT is a REAL question. There is too much handwaving and smoke (ie we can't tell you). So I would not be supprised that if you are thinking DECT, don't worry about WEP over WPA. Push for DTLS for security in mobile devices. Of course that needs Diffie-Hellman and they scream about that. Though the ECC variant is already used for GSM, so there is hope. And don't even mention RSA operations. But again we do see some of the ECC alogrithms in GSM devices; most of the manufactures in the GSM field are willing to pay the patent royalties demanded. ___ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

The Nokia SIP client isn't particularly impressive. However, most of its problems can be solved by telling the phone to use Asterisk as a proxy and not fill out the register settings (except server, which should just be sip:asterisk). This is obviously wrong, as Asterisk isn't a SIP proxy, but it works. NAT is a problem; you cannot specify STUN servers, but the phone will try to find them based on SRV records on the server address you specify. It will also try the default STUN port on the SIP server. /Benny ___ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [asterisk-users] Recommendations for 100 Wifi SIP phone setup
Hi, 1. Is your WiFi network dedicated to VoIP or shared with data applications ? How was it designed ? For people using WiFi with a laptop, you propably don't need to have dense WiFi cells as moving from one cell should be scarce. With hand phones, those cells should overlap as it becomes very likely users would to move from one location to another while on the phone. 2. From this list, the WiFi hardphones which got only positive answers where Siemens Gigaset SL75 and Nokia EXX Series.

Re: [asterisk-users] Recommendations for 100 Wifi SIP phone setup
For campus installations such as this, you may want to look at Polycom (Spectralink) phones. They are more expensive but are designed for tough environments and are of better quality than any of the consumer-oriented phones. Asterisk should be fine for an installation of this size, no need for SER. You can even set this up without registering the endpoints because they will be on a LAN and you can use static LAN IPs for each individual phone. Beyond technical considerations, you will have to be very aware of practical matters such as broken phones and stolen phones. In hospitals you can pretty much bet on replacing your total phone pool every year, so when installing a system like this you are not buying 100 phones, you are buying 100 phones PER YEAR. In a hotel I can imagine it would be even worse in terms of stolen phones. - Original Message - From: <[EMAIL PROTECTED]> To: "Asterisk Users Mailing List - Non-Commercial Discussion" Sent: Sunday, November 25, 2007 3:26 PM Subject: [asterisk-users] Recommendations for 100 Wifi SIP phone setup > Hi all, > > > Im preparing a quote for a 5 Star hotel, planning to have around 100 > SIP Wifi phones for PBX operations running on 100 AccessPoints. > Network is running in ARUBA Networks - AP70 access points. > > The initial recommendation is to go for Hitachi Wifiphones, but i > would like to know from the group the recommendations.

Re: [asterisk-users] Recommendations for 100 Wifi SIP phone setup
My number one recommendation is be VERY VERY Careful. You could be selling the biggest nightmare to you and the customer ever. I have tried almost all the wifi sip phones and they are ALL sub par. Range is terrible on most, but mainly its staying connected to the ap's all the time and especially multiaccess points that causes issues. The hitachi phone I tried, the 5000, it was bad, it doesn't support wpa, that's crazy. No firmware updates in a while either so its not coming. The new one maybe does, the ae. The utstarcom one never stayed connected either. Anyways the best is what the other guy said, phones that are not wifi but integrated with sip, that might be worth looking into. I assume the hotel already has the access points that's why you are doing this? Well I can see the reason, my recommendation, do extensive testing first with the phones you are looking at, as in multi day testing to make sure the phones stay connected and get all the calls.

Any specific Issues? > >Any such installations done? Please do a detail I had some Hitachi WIP5000 back in early 2006. It looks like a nice device but it really didn't deliver upon its promise. The reason to select a wifi phone is that by staying IP end to end you might gain operational advantages. It should have at least some of the features of a proper SIP deskset. The WIP5000 did not provide this at the time. The phones that I used had simple trouble moving between access points. Also the volume of the earpiece was very low, even for use in a quiet office. I am led to beleive that the new DECT cordless IP devices, like the system from Aastra Telecom, are currently a better option than wifi devices.
