[Asterisk-Users] vonage.ca * integration possible?

asterisk at dreamwerx.net asterisk at dreamwerx.net
Fri Jul 9 07:28:06 MST 2004


I just got setup with vonage.ca with the motorola ata unit.. I fired up
ethreal and checked out what's flying over the network...  The sniff below
would lead me to believe that it might be possible to have asterisk spoof
the User-Agent field and register itself?

Any thoughts/feedback?  Thanks.
