Shawn, can you describe what the phone needs to see to start contacting the PPM server for more than just ‘getInitialEndpointConfiguration’? I’m trying to implement correct replies for my SIP proxy but I’m having trouble following your Asterisk patch to make sense of it all.
I see the phone sends SUBSCRIBE with Event: avaya-cm-feature-status but I don’t really know what to do from here. I can send 202 Accepted but then do I need to send NOTIFY? What headers/info do I need to send in NOTIFY? Do you happen to have traces you can upload of what the SIP dialogue should look like to enable each feature?
