I am running Asterisk 1.4.22 I have successfully installed everything with multiple extensions and can make and receive calls internally and externally.
How would I go about receiving an anonymous SIP call and routing it to one of my SIP trunks within my outbound routes?
Would I need to setup an extension to handle this call and redirect it?
Annon calls go to the default context that you set in sip.conf. In extensions.conf under that context I usually have a catch all and direct it to my main incoming context.
