We try to use jitsi with an aastra 5000 as sip server.
After 30 sec the sip server send me a "request: INFO", jitsi respond
"Status: 501 Not implemented" then the server send the request "BYE" and
the call end.
We're not able to establish a call during more than 30sec.
Is there a way that jitsi send a 200 OK instead of an 501 to a SIP INFO
The aastra 5000 use the sip info as a keep-alive.
Thanks for your answer
