Thanks for the prompt response. I've tried changing the STUN server as well as setting outbound proxy (I even tried the proxy settings as described in the guide). Yet wasn't successful
.
Is there anyone who has tested voxalot incoming on a PAP2T? I just want to confirm that this is some issue with PAP2T+Voxalot. I have configured many PAP2T phones (though none with Voxalot) so far and this is the first time I am facing audio issues even after setting STUN and NAT mapping.
Any more suggestions?
