I have the Acrobits Groundwire softphone running on an IPhone (ATT).
My FreePBX is on a routable IP.
The Groundwire will register with no problems. In FreePBX I see the Extension registered with a Host address of 10.98.127.9 and the Port Status as “unreachable”.
I can make inbound calls from the softphone and the receiving party can hear me but I cannot hear them. The Acrobits software identified that there was a one-way audio issue and by purchasing their $.99 monthly NAT Bridge service the problem would be resolved.
- The problem wasn’t resolved. Except the message went away.
- How does this ever work to allow calls to be made to this phone when it has an internal IP and is “unreachable”.
I cannot be the only person having these issues.
This is the kind of problems I seem to have with any SIP phone behind a firewall/router.
Any ideas? I am missing some basic concept.
