Yeah, what's the network look like? Is fs behind nat or the clients or both? Fs is usually VERY good at overcoming NAT issues. You might want to set the ext-sip-ip and rtp-ip to the public ip if fs is behind nat.

Recently we are testing the Freeswitch with the Astpp for change us servers (we use asterisk with a2billing).
In the migration process, we check some customers don’t register or don’t receive inbound calls. In a2billing works fine.
I think is something about NAT. Someone help me?


Atenciosamente,
