When I send an inbound call to a PSTN extension (my mobile phone, part of a ring group) and pick up the PSTN, the call connects but I get no audio.
I'm about 98% sure this is a double NAT issue, as the PBX is behind a firewall.
The firewall does have siproxd, which works as a sip proxy at the firewall - so no NAT at all.
I'm wondering what I have to change in the PBX to make this work.
As best as I can figure
asterisk SIP settings: NAT set to "never"
In my vitelity trunks (vitelity has you set up separate outbound and inbound trunks)
nat=no
outboundproxy=[firewall LAN address]
What am I missing?
Thanks!
