[asterisk-users] polycom phone behind firewall with asterisk 11.19

[Jerry Geis]

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
