Call Forwarding Busy Issue

Here is the scenario. The main office phone is an AT&T landline, which if busy, is configured to dial a sip line, call it XXX-XXX-XXXX <sip 1 number>. This works just fine, as long as the XXX-XXX-XXXX <sip 1 number> is not busy. XXX-XXX-XXXX <sip 1 number> is set to forward to YYY-YYY-YYYY <sip 2 number> if SIP1 is busy, but this never works. The AT&T line never makes it to SIP2, if SIP1 is busy.

Any idea how to fix that, or a better work-around to accomplish the jist of the idea.?


Unless someone knows a better way, I will try a queue see if that solves the problem.

Generally you need to pay AT&T individually for each “call path” so for two concurrent calls being forwarded you will need 2 cf paths.

Interesting, I will call AT&T later this morning and check on that, thanks!
