For example I have created one sip user and I made two contexts in extension.conf. This user has 2 contexts and these contexts are context-1 and context-2.
My question is when user try to call 100 with his ip phone so how does behave asterisk.
1-this user only calls user1
2- this user only calls user2
3-this user call both of user1 and user2
4-none of them. Asterisk gives error message when dial plan loaded?
exten => 100,1,Dial(SIP/Client1)
exten => 100,1,Dial(SIP/Client2)
