If all calls go like this, usage of a rtp relay (rttpproxy/mediaproxy)
is no longer necessary -- I see in the config you call use_media_proxy()
- asterisk will handle media relay if it has public ip if the nat option
is enabled in asterisk as David says.
Cheers,
Daniel

Hi mates,
I have this setup:
Xlite---->Openser---->Asterisk------>VoIP to PTSN Provider
I use kamailio 1.3.3(port5060), MediaProxy and Asterisk 1.4 (port
5065) on the same Debian Box in Realtime with no NAT. Asterisk
connects calls to the VoIP to PSTN provider. I am able to
establish calls towards the PSTN side(Landline & Mobiles) but
with no audio. I can hear the ringing tone but when the call
connects and the conversation begin i hear nothing so as the
Callee side.
Below are my configs,the ngrep captured packets and codecs.
