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.
