[VoIP] Asterisk Dialplan Question

[Jack Ryan]

Greg,

If you use that method and the callee is engaged or does not answer, don't
you then try again using the next available outside line? Maybe you do but
it doesn't matter - unless the outside is gsm (mobile).

(I'm a bit green as an asterisk user so to me the obvious isn't)

Thanks

Jack
