I have a situation where I make a call to a pstn provider, everything works correctly on the SIP level, INVITEs, OKs, ACKs and BYEs are all passing correctly through my server, but for some reason, I'm unable to get audio to work correctly on both sides.
At the moment I'm using Openser 1.1.0 with mediaproxy (and a slightly modified openser.cfg based on the mediaproxy one on the openser site, I have a some options for accounting and forwarding to the pstn gateway)..
89.x.x.16 is my openser server.
89.x.x.8 is my NAT firewall, which is portforwarding all UDP from 5000 to 30000 to 192.168.1.67 (my internal machine, with X-Lite).
x.x.x.53 is my PSTN provider's SIP server
x.x.x.3 is my PSTN provider's media server.
this is the SIP dialog:

Can anyone see something irregular in this dialog?
Or do I need to start beating up my firewall/NAT ?
The media IP of the SDP in the INVITE is not changed to the public, it stays private which means that it was not processed by nat traversal logic. There should be a mistake in the configuration script.
Cheers, Daniel

Can anyone see something irregular in this dialog?
Or do I need to start beating up my firewall/NAT ?

^^^^^^^^^^^^^^^^^^^^^^^^^^
This is my problem, right here.
I've found the correct way to correct the problem, fix_nated_spd(); but I'm not sure where in my routing logic I need to put it..
If needed I can send my openser.cfg, I just need to be able to fix the SDP NATing.
t=0 0. m=audio 13234 RTP/AVP 0 98 3 101. a=alt:1 1 : AtyyaMHs +WwsY5o+ 192.168.1.67 13234. a=fmtp:101 0-15. a=rtpmap:98 iLBC/8000. a=rtpmap:101 telephone-event/8000. a=sendrecv.
I am not using mediaproxy currently, so I do not know if you need to use functions from nathelper. However, you should call fix_nated_sdp() for the INVITE and 183/200 replies. Looking at next configs together might help:

This is my problem, right here.
I've found the correct way to correct the problem, fix_nated_spd(); but I'm not sure where in my routing logic I need to put it..
If needed I can send my openser.cfg, I just need to be able to fix the SDP NATing.

I am not using mediaproxy currently, so I do not know if you need to use functions from nathelper. However, you should call fix_nated_sdp() for the INVITE and 183/200 replies. Looking at next configs together might help:

I have a situation where I make a call to a pstn provider, everything works correctly on the SIP level, INVITEs, OKs, ACKs and BYEs are all passing correctly through my server, but for some reason, I'm unable to get audio to work correctly on both sides.
At the moment I'm using Openser 1.1.0 with mediaproxy (and a slightly modified openser.cfg based on the mediaproxy one on the openser site, I have a some options for accounting and forwarding to the pstn gateway)..
89.x.x.16 is my openser server.
89.x.x.8 is my NAT firewall, which is portforwarding all UDP from 5000 to 30000 to 192.168.1.67 (my internal machine, with X-Lite).
x.x.x.53 is my PSTN provider's SIP server
x.x.x.3 is my PSTN provider's media server.
this is the SIP dialog:
