[Asterisk-Users] IAX2 NAT / Registration Issue

[Steven Sokol]

I have a client using IAX Phone at his office to connect to his Asterisk
located at a data center.  His IAX Phone connects through his office NAT
gateway device (unfortunately I don't know the specific brand and model).
He can make calls just fine.  However, he seems to have issues receiving
calls.

I monitored his Asterisk for a bit and noticed that his IAX Phone, which
registers every 60 seconds, always registers from a different port.  Does
this indicate that 60 seconds is too long, and that the NAT is closing the
hole between registrations?

I will try to find out what type of router/gateway he is using and post it.

Any thoughts would be appreciated.
