FreePBX w/ AudioCodes MP-118 Roll Over for Incoming Lines

I am setting up a new FreePBX system. I am setting up an Audiocodes MP-118 (x8 FXO) Gateway to work as the incoming and outgoing lines.

I need 3 of the lines to roll over if the main business phone number line is busy.

Do I need to set that up through the telephone provider, or can the Audiocodes handle that? I am thinking that I will have to set it out through the phone company, but wanted to see if the Audiocodes Gateway could do that for me instead.


The line will busy-out when it is in use. Roll-over/hunt-group is only available from your provider.
