[Asterisk-Dev] Does Asterisk support SIP proxy authentication?

[Chris Caston]

Hello,

I have a similar question to this that was posted in 2002:

http://www.marko.net/asterisk/archives/0210/0137.html

I would like to register with an upstream SIP provider that gives me a
standard POTS phone number and allows me to make calls to people on the
PSTN.

I have adsl with 1 static IP and my network is behind NAT.

I think their machine is a Cisco call manager.

thanks,

Chris
