I have a polycom phone behind a firewall. The phone registers – but I only hear half channel audio.

I have tried nat=yes, nat=force_rport,comedia and nat=autio_force_rport,auto_comedia (reloading asterisk every time).

made no difference.

How might I get full audio path?

Thanks,

Jerry

  • What version of Asterisk?
    Which half can you hear?

    After a recent update I had a problem with one way audio. Maybe you are having the same problem. See the recent thread on one way audio started by me with my solution.
