Hi Robert,
I placed a call from 2.3 to 2.5(gail) to observe the traffic. Then I place a call from 2.3 to gail@2.10 to observe the traffic through openser.
For the network topology, it's all on the same local network. I tried the default cfg file and it works fine. I'll try adjusting nat_uac_test, as it's not recognizing I'm on the local network.
All set, Thanks!

The pro's seem to be busy so I'll give it a go.
If gail == 2.5 then a call from 2.5 to gail does not make much sense but maybe it was a typo.
You did not say anything about your topology. Where were expecting to find the RTP packets?
uac test 19 ( really 16+2+1 ) maybe isn't really what you want. Check the nathelper documentation. Among other things it will check for a private address. If you have local to local calls, there is no NAT involved. Sending
the RTP through a proxy is unnecessary. It probably would work though.

Hello,
Following
http://www.voip-info.org/wiki/index.php?page=OpenSER%20v1.2.x%20and%20RTPPr
o xy and cleaning up the errors in the log, I have OpenSER 1.3 and RTPProxy running in my local domain (192.168.2.10)
I have two SIP phones in my local domain, on two machines. (2.5 and 2.3)
I added an alias via openserctl ul add gail sip:192.168.2.5
Looking at the packets captured from a call between 2.5 and 2.3, 2.3
should
start streaming RTP packets after it ACKs the 200 from 2.5
I call from 192.168.2.5 to gail@192.168.2.10 and the connection is established between the three, but no RTP streams ever begin. I expected to see 2.3 streaming RTP after it ACKs the 200 from 2.10.
Any suggestions?
Here's my cfg file:
