I setup ITSP Profile A General:SignalingProtocol to SIP
Under SIP, I changed the ProxyServer to the domain name of my Asterisk server
Under Voice Services SP1 service, I added my extension number and password.
The extension does register, but it doesn't stay registered. When it is registered, I can call the extension from another extension in the system. However, I cannot make any outgoing calls from the extension. Eventually, I get a message indicating the the Asterisk server isn't responding.
I've set up SPA3102, PAP2, and handytone 286's up as extensions with no problems, but this doesn't seem to work.
Thanks,
Steve
