[OpenSER-Users] OpenSerand RTPProxy, no RTP audio

[Eric Phetteplace]

Hello,

Following
http://www.voip-info.org/wiki/index.php?page=OpenSER%20v1.2.x%20and%20RTPPro
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 at 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:

#
# sample config file to be used with nathelper/rtpproxy
#
# start RTPProxy with: rtpproxy -l your_public_ip -s udp:localhost:8899
#

# ----------- global configuration parameters ------------------------
