[OpenSER-Users] Missing RTP stream

20 Sep 2007

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:
