[asterisk-users] SIP fails to register

[Zaheer K. Master]

Hi Joe,
In your SIP.conf, under [general] try setting "externip=XXX.XXX.XXX.XXX" to
your public IP address.

Hope this helps,
Zaheer

Subject: [asterisk-users] SIP fails to register

Trying to setup SIP to register with a VOIP provider.  I am behind a
firewall (IPCOP) with NAT.

Getting this, in CLI with SIP debug on.

Retransmitting #2 (no NAT) to aa.bbb.ccc.ddd:5060:
REGISTER sip:voip-xxx.com SIP/2.0
Via: SIP/2.0/UDP 192.168.0.xxx:5060;branch=z9hG4bK727a6144;rport
From: <sip:me at voip-xx.com>;tag=eufhksk
To: <sip:me at voip-xx.com>
Call-ID: alongnumber at 192.168.0.xxx
CSeq: 103 REGISTER
User-Agent: Asterisk PBX
Max-Forwards: 70
Expires: 120
Contact: <sip:s at 192.168.0.xxx>
Event: registration
Content-Length: 0

I suspect there is something, somewhere, where I can tell it the "Contact"
should in fact be my public IP, not the local IP.

Anyone know?  Or know what else it might be?  I am almost 100% certain my
credentials are correct.
