<br>
thank you, that did the trick! <br>
I added a pre_aswer, a playback and finally a ring_ready in order
to playback a ring tone to the caller. Now we have 2 way audio.<br>
<br>
Best regards<br>

<br>
I have the following scenario<br>
<ul>
<li>Freeswitch is behind NAT with external profile with
ext_sip_ip and ext_rtp_ip</li>
<li>Echo from an external SIP provider test inbound
works with audio</li>
<li>Calling outbound to the same external SIP provider
works with audio</li>
<li><b>Receiving a call from the external SIP provider
and bridging it to another number at the same
external SIP provider does not have audio</b></li>
<li>Receiving a call from the external SIP provider and
bridging it to a local Patton PRI works with audio</li>
</ul>
<p>I also set up another (modified NAT) profile<br>
</p>
<ul>
<li>like external profile - but with a different
ext_rtp_ip </li>
<li>calling outbound to via NAT profile to another SIP
provider works with audio</li>
<li><b>Receiving a call from the external SIP provider
(external profile) and bridging it to another
number </b><b>at the another external SIP provider </b><b><b>(nat</b><b><b>
profile)</b></b> does not have audio</b></li>
<li>Tcpdump btw. does not show an attempt of Freeswitch
to issue any outbound RTP packet. I can see only SIP
messages towards the outbound SIP provider<b><br>
</b></li>
</ul>
<p>So I think, there is a problem with briding a natted
external call to another natted external call, both
with ext-rtp-ip. It tried this on an older Freeswitch (1
year old) and with a more recent Freeswitch (1 month
old), both behave the same. Same scenario with a
non-natted Freeswitch works fine. <br>
Btw. Freeswitch logs do show <br>
RTCPpacket not written<br>
right after bridginbg the call.<br>
</p>
<p>Question: Does anybody have a clue, what could cause
the problem? Maybe there is any parameter in the
profiles, that may help?<span class="HOEnZb"><font
