I have setup an asterisk server 1.4.27. With that i have a sip accout with 4 channels and 4 telephone numbers.
Every is working like incomming calls and out going as well.
But incomming only works if i have this in extensions.conf exten = s,1,Goto(ringroups-custum-1|s|1) so catch all
If i change s into _X. i get a busy tone when i dail the incomming number my understanding is that _X. is also catch all.
the thing is we use 3 numbers for ex xxxxxxxx70, xxxxxxxx71, xxxxxxxx72 the 70 and 71 number should go to extension 100 and 101 and numer 72 needs to go to extension 200.
what can i do to get this working as the incoming calling rule only works with s(catch all).
