-----------------------------------------------

Hello.

Thanks for this great work.
I have a 9971 cisco phone with camera, asterisk11.3 and freepbx on Raspberry Pi and an E169 GSM dongle

I've applied the patch and cisco is running much better with BLF activated but when I try to add the GSM dongle to the system and installed the files provided at
https://code.google.com/p/asterisk-chan-dongle/
https://github.com/marcelloceschia/chan-datacard

the system would run with no problem internally until I start using the GSM dongle (incoming call). Asterisk simply just crash and restart. the dongle work fine on unpatched Asterisk.

cli extraction during an incoming call can be found here
unpatched: http://pastebin.com/yS7bPPvD
patched: http://pastebin.com/gyajLqEh

I tried also having the incoming gsm call directed to an extension with a softphone attached to it and also I get the same crash.

sms and ussd are received with no problem. so it is only when calling+presence.
can anyone kindly help on this if there is a simple workaround config setting or can this incompatibility be fixed in future patches.

thanks everyone

> Cisco phones appear to be unable to parse the existing PIDF XML being generated by Asterisk for presence notification.  I've attached a patch which produces well-formed (but incomplete) XML which will satisfy a Cisco phone.  The patch as supplied will successfully render a "busy" subscription, but does not send a subsequent "available" notification, so presence detection only half works currently.
> I suspect the next step might be to watch some CallManager SIP traffic to identify precisely what XML tags the phone is expecting in order to properly parse an available subscription, but I'm not in a position to do that.  I'll continue to work with this, though, and perhaps may be able to stumble upon the precise data the Cisco phone is looking for.
> ****** ADDITIONAL INFORMATION ******
> I believe that this requires the Cisco phones be configured to use SIP TCP when connecting to Asterisk.
