asterisk users - Dec 2010 - Wise selecting of outgoing channel

Hi.

We have 3 channel for _outgoing_ calls and would like to use them equally (by
turn).

Is there any 'queue' for outgoing calls? Now I have to select the second
channel manually when the first is busy and so on.

Does Asterisk have any functionality to do it automatically?

That's what the G and R functions of dial are for.  Dial(DAHDI/G1) selects
the 3 lines in reverse order (3,2,1).  Dial(DAHDI/g1) selects them in
ascending order (123).  Dial(DAHDI/r1) is "round-robin" and
Dial(DAHDI/R1)
is "round-robin-reverse".  This is defined in the Asterisk Guide.
