Re: [OpenSER-Users] Missing RTP stream

20 Sep 2007

Hi Morten,

Admittedly, I haven't looked closely at your trace.  However, based on
the description you gave, the first place to look is at the "canrevite"
setting in Asterisk sip.conf.  You might want to try "canreinvite=no"
after reading up on this particular setting.

Regards,
Norm

  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:
