Calls to the main number go to line 1 (ext 101). Easy enough to do, skip the auto receptionist, send all calls to extension 101. If line 1 is busy, then try line 2. This also seemed easy, just add a second line to extension 101 and have the calls be forwarded sequentially. Here is where it gets tricky. If line 2 doesn't answer, then we'd like the call to be sent to voicemail, not try lines 3 and 4.
To phrase it differently, we'd like the call to go to VM if it's not answered, only forwarded to the next line if the line is busy. Our current phone provider (Comcast) calls this a "Hunt Group".
I've been reading docs over the last few days, and it seems like Call Queues is the answer, but it brings a load of more complex issues/rules with custom hours/greetings.
Is there a way to accomplish this?
Thanks in advance.
edit: I should mention we'd be using analog phones via ATAs. I've purposely left this vague in hopes that simplifying the issue makes it easier to understand, but I'll be happy to provide whatever more details are needed.
