<p>Hello,</p>
<p>you have to instruct rtpengine to do bridging between the two
network interfaces.</p>
<p>Can you show the INVITE and the 200ok with all SDPs, both sides
(incoming and outgoing to/from kamailio), for the case you get
audio problem? Then we can confirm if the SDP has been updated
properly for bridging.</p>
<p>Cheers,<br>
Daniel<br>

<p class="MsoNormal">Hi <o:p></o:p></p>

<p class="MsoNormal">Thanks in advance if anyone can point me in
the correct direction .<o:p></o:p></p>
<p class="MsoNormal">I have kamailio running in front of some
asterisk VM’s. SIP endpoint register to their asterisk PBX
via Kamailio dispatcher module. I’m running rtpengine with a
Wan and private interface to bridge audio stream between these
endpoints on the WAN to asterisk PBX running on LAN IP behind
Kamailio.<o:p></o:p></p>
<p class="MsoNormal">Calls from ext to ext work fine audio both
directions , calls outbound to PSTN via SIP trunk to SIP
provider via trunk on asterisk work fine audio both
directions. But incoming calls via SIP provider I only get
audio on stream from asterisk registered ext to external
caller , no audio from external caller to the asterisk ext.<o:p></o:p></p>
<p class="MsoNormal">I reckon I have something wrong in my
Kamailio.cfg . if I register an ext direct to asterisk I get
audio both ways on incoming calls. And rtp logs from
rtpenegine show it as trying to send the rtp to the private
address of the sip endpoint rather that its WAN address.<o:p></o:p></p>
<p class="MsoNormal">I think my mistake in somewhere in the cfg
below. <o:p></o:p></p>
<p class="MsoNormal">Do I need to handle invites from the
backend asterisk servers different that invites from sip
endpoints?<o:p></o:p></p>
