Dan Carlson commented on ASTERISK-13145:
----------------------------------------

@Dinesh: I'm currently on version FreePBX 5.211.65-13 with Asterisk 11.9.0.  Maybe I'll give it another shot.  Upon patching the 11.9 asterisk source with Gareth's patch and installing, everything did not appear to be functioning as had before.  The logs were filled with tons of errors and some of the functionality seemed to be broken after.

After reading some forums on the FreePBX site, it seemed the consensus was that it was not a good idea to try and install from source on a distro.

> 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.
