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

Hello...  I have successfully applied Gareth's patch on 11.6.0, and I am trying to get it to work with my cisco 7961 running SIP41.9-3-1SR4-1S, however I can't get it to work.

The phone subscribes correctly, and I even get a notification back to the phone (as shown by sip set debug on), however the phone line light state does not change.

My SEP file config contains:

{code}
         <line button="6">
           <featureID>21</featureID>
           <featureLabel>MyLabel</featureLabel>
           <speedDialNumber>extension#</speedDialNumber>
           <featureOptionMask>1</featureOptionMask>
         </line>
{code}

my subscriptions look like:

{code}
Peer             User             Call ID          Extension        Last state     Type            Mailbox    Expiry
cisco-phone    user        001e7ac5-929d00  extension#@presence     Idle           cpim-pidf+xml   <none>     003600
{code}

My "presence" extension:

{code}
[presence]
exten = extension#,hint,SIP/extension#
{code}

Any suggestions on how to debug this?  I'd be happy to provide any information needed.  Thanks.

> 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.
