[asterisk-users] SPA-2102 sending local IP instead of WAN IP in SIP packets

[bruce bruce]

And that is exactly what is done on the device: Nat=yes but Asterisk still
sees the SIP packet coming in to register with a local IP an so it responds
to a local IP which doesn't even exist on the Asterisk network. This is what
frustrates me that it's not so straight forward to Asterisk to obtain the
proper public IP of the device from the IP packet headers rather than the
SIP packets.

Thanks
