[asterisk-users] sequential dialing preferences

[Thomas Perron]

I am trying to use a simple tool in the Dial plan so that if the first
number does not connect the logic will go to the second and/or third.

Basically, I want the call to ring and connect to the first number
Then, if it is not answered I want another number to try to get connected
Then, if second number does not answer I want the third to be tried
i only list the scenario for the first two numbers

Here is what I have now which works fine for the one and only number...........

exten => s,n,Dial(SIP/callwithus/12135551212,120,A(ginger3)) ;   Service line

so, will this work ........... ???? ..........

exten => s,n,Dial(SIP/callwithus/12135551212[&SIP/callwithus/12145551212],120,A(ginger3))
;  Service line

Please send comments to make this work.
Thanks
