Greetings,
I have a problem getting Asterisk registered as a UAC against the
MetaSwitch call agent, because the customer insists on running it on a
NAT'd box. Thus, the Contact: field in the REGISTER request betrays
the private IP address of the Asterisk box, but the source IP of the
message is a public one.
Most registrars don't have a problem with this, including Asterisk.
However, MetaSwitch doesn't like that; it expects (whether doing
IP-trust or user authentication) to contact the SIP peer at such and
such IP address in the SIP binding, and expects that's what the Contact:
reachability information will be too.
Any way to overcome this in Asterisk? I thought about the externip=
option but it did not seem to work from an internal test box that is
not behind NAT.
Thanks,
-- Alex
