I have had mixed success with Groundwire PUSH proxy with PJSIP. Sometimes, i get no audio on both sides, while at other occasions calls work fine. For the latter case, i have noticed that the PUSH server takes itself out of the signalling path,
-- PJSIP/202-0000006a is ringing -- Added contact 'sips:[email protected]:57018;transport=TLS;rinstance=7E640171' to AOR '202' with expiration of 600 seconds -- Removed contact 'sips:[email protected]:59030;transport=TLS;rinstance=3256F4C9;x-ast-orig-host=10.65.11.4:59030' from AOR '202' due to remove existing == Contact 202/sips:[email protected]:59030;transport=TLS;rinstance=3256F4C9;x-ast-orig-host=10.65.11.4:59030 has been deleted == Endpoint 202 is now Unreachable == Endpoint 202 is now Reachable -- Contact 202/sips:[email protected]:57018;transport=TLS;rinstance=7E640171 is now Reachable. RTT: 152.468 msec
This behavior is in conflict to what they claim,
Once you accept the Push Notification, Acrobits Softphone or Groundwire will open and SIPIS will connect the call to your device. At this point SIP Traffic will continue to be routed through SIPIS, while audio will go directly to the device.
Anybody using Groundwire wants to weigh in what is the expected behavior?
