Subject: [sipxtapi-dev] Not seeing outbound RTP packets
I have an application that is modeled after placecall/receivecall. I am able
to successfully able to connect to/from a remote sip client (xlite) from my
application. Once I connect I am able to hear the audio that is streaming from
that client. However I am not seeing RTP traffic coming from my client to the
remote client. The RTP traffic only seems to come from the remote client into
my application.
I have captured some of the traffic with wireshark. I posted both of the
images on photobucket at the following links (I wasnt sure if it was ok to
attach these images to this e-mail):

In these images the my client is 172.21.6.115. The remote client (xlite) is
at 172.21.3.120. The sip server is at 172.21.6.218. Notice in the first image I
have highlighted a single line showing an "unknown RTP version" packet going
from my client to the xlite client. This is the only RTP traffic that I seem to
see. Notice that there is a lot of RTP traffic coming from the xlite client
(120) to mine. That, of course, is why I can hear the audio coming from xlite,
but it cant hear any audio coming from me.
Why do you think my application not sending RTP packets?
I need packets to go out, because the remote application (not xlite.. just
testing with xlite) will shut down the connection if it does not receive RTP.
Thanks in advance.
