In scenario 1 calls from the cellphone using a SIP
softphone app go
through 100% of the time with both endpoints of the call being audible.
However in scenario 2, calls from the cellphone go through with both
endpoints of the call being audible only sometimes, and during all other
attempts, call goes through with no voice from the cellphone.
i have noticed the same thing with some nokia phones. if nokia receives
200 ok, it should start sending audio, but looks like sometimes it
doesn't, since your rtpproxy is not receiving any.
have you checked if in those cases, nokia has sent ACK to kamailio or is
it re-sending the invite?
