Here's the registration for a Phone and the ATA. I'm going to peak in
the Linksys configuration for SIP configuration.

sip:[email protected]        <sip:[email protected];x-sipX-nonat>       2214
sip:[email protected]        
<sip:[email protected]:15060;x-sipX-privcontact=192.168.15.101>   
771

Thanks,
Max
