[Asterisk-Users] A room full of Cisco 7960s behind NAT

[Ed Greenberg]

I need to set up an office full of Cisco 7960 phones behind NAT with the 
server out in Colo.

The first test phone registers fine, but the second one does not register.



The first phone's registration looks like so:
/SIP/Registry/3115552368
	:64.169.xx.yyy:38836:3600:3115552368:sip:3115552368 at 64.169.xx.yyy:5060

When the second phone tries to register, it gets back a 404 not found. Not 
a 401, Authentication Required.

The error in the full log is:Feb 28 14:26:27 NOTICE[4888] chan_sip.c: 
Registration from 'sip:8115552368 at ev01b.networkpts.com' failed
 for '64.169.xx.yyy' - Username/auth name mismatch

What's the right way to do this. Shown below are my configuration files:

-----SIPDefault and SIPMacAddr -----

My NatTwo phone is similar. The only difference is the name/password using 
8115552368.
