[asterisk-users] Re: How to separate outgoing extens from the contexts from sip.conf?

[Eric "ManxPower" Wieling]

Put your phones in the context=toll-access in sip.conf or zapata.conf
Put the phone "lines" in context=incoming in sip.conf or zapata.conf

extensions.conf:

[extensions]

exten => 667,1,Dial(SIP/whatever)
...
more exten lines to dial your phones here

[incoming] ; this is where calls from untrusted sources should land

include => extensons

[toll-trunks]

exten => _91NXXNXXXXXX,1,Dial(Zap/g1/${EXTEN:1}
...
more exten lines to dial outside numbers here

[toll-access]

include => extensions
inclide => toll-trunks
