<div text="#000000" bgcolor="#FFFFFF"> Hi Brian,<br>
<br>
it seems that this was not the issue.<br>
<br>
Some more details:<br>
We have an opensips server using the load_balancer module
to route the calls to the freeswitch box. (<a href="https://wiki.freeswitch.org/wiki/Enterprise_deployment_OpenSIPS" target="_blank">https://wiki.freeswitch.org/wiki/Enterprise_deployment_OpenSIPS</a>)<br>
When I route the calls directly to the freeswitch's
external IP, the calls connect fine and have audio.<br>
However when I route the calls to the opensips server
first, the call will connect but without audio. <br>
<br>
The strange thing is Opensips uses Freeswitch's internal
address (from the load_balancer table) to forward the
INVITE packet, yet when the ACK packet comes in from the
provider opensips tries to forward it to the FS external
IP address rather than the internal IP.<br>
<br>
I understand this is probably more an opensips question,
so will understand if I should post this to their mailing
list, but any tips would be appreciated. <br>
<br>
<br>

does it make any difference if my internal

the SDP connection information? I have 2

can bridge calls but get no<br>

Even with the below settings the SDP message
