Dialing *72 through provider rather than Asterisk phone system.
Posted on 2014-04-01
I am using FreePBX 2.11 on Asterisk 11.7 with a 4-port analog card and DAHDI. We would like to be able to allow users to dial *72 and *73 to forward/unforward calls at the provider level instead of through the phone system, and only on line 3.
For example, someone picks up the phone and dials *72. This opens up an outside line to line 3 and dials *72 outbound through line 3. They get Comcast's call forwarding prompts and when finished they hang up. To remove the call forwarding on line 3, they dial *73 which dials out through the third line and uses Comcasts system to remove the call forwarding.
How can I do this? Thanks
