sdpops: new function sdp_get_ip_c
by Vicente Hernando 13 Sep '12

13 Sep '12

Hello, attached patch shows a new function in sdpops module: sdp_get_ip_c It receives as parameter an avp variable, and stores there every connection IP for each stream. If a stream has not c IP, then it returns session default one. Any opinion or criticism? Kind regards, Vicente.

git:master: usrloc(k): keep time of the last keepalive for natted UDP contacts
by Juha Heinanen 13 Sep '12

13 Sep '12

Klaus wrote: Why only UDP? Are TCP contacts removed when the TCP connections is closed? IMO there should also be a mechanism to remove ALL expired unresponsive contacts. how about the following for tcp contacts: - set_forward_no_connect(); - if t_relay() fails because tcp connection does not exist, unregister the AoR/contact what would be needed is a find out that t_relay() failed due to non-existing connection and a script function to do un-registration of an AoR/contact. perhaps both of these two things already exist? -- juha
