Hi!
I have a strange problem with a missing RTP stream between OpenSER and Asterisk. I am not sure if it is OpenSER og Asterisk related.
I have this setup
Phone A (172.17.96.17) -- \ Openser -- Asterisk -- PSTN / (192.168.0.6) (192.168.0.3) Phone B (172.17.96.10) -- (172.17.64.1)
I also have a Mediaproxy running on OpenSER and I force every call to use the Mediaproxy.
I call from Phone A or B to the PSTN works fine and from PSTN to Phone A or B it also works.
I have the dialplan logic on my Asterisk server so I want calls from Phone A to Phone B to pass the Asterisk server. And this is were I have the problem. When the call is established the RTP stream is missing between Mediaproxy and Asterisk. I only have a RTP stream between the phones and Mediaproxy. As far as I can see the SIP signalling is correct.
The SIP traces is listed below. Can you spot the problem in this?
I will buy a beer (or 5) at OpenSER training in Rome to anyone who can help me solve this problem.
SIP trace between the phones and OpenSER:
