We just installed an Asterisk PBX for a customer and there is one last piece of the puzzle that we cannot seem to figure out. EE has yet to fail me so I have confidence that someone has the answer.
The customer used to forward their calls to an answering service using the call forward codes on the lines. We also changed them over to a PRI so now we have to forward the lines inside the system using a trunk-to-trunk connection. We were able to get a quick fix by forwarding one of the phones that rings manually. The problem is that when the receptionist leaves, she used to forward the calls to where they would ring everywhere so someone who was still in the building could answer the call then when the last person would leave, they would forward the calls to the answering service. I was hoping somebody knew of a way to call forward a phone from another extension or use a code to change the destination of an incoming call, what we typically call "night service".
In our research we couldn't find anything where Asterisk offered sifferent ringing modes. We were thinking we might have to build some sort of macro to modify the destinations in the extensions.conf file but we didn't know if there was a better or easier way to accomplish this.
