Just wondering if anyone has any ideas around a problem that I've hit.
Currently there is a system that has all incoming and outgoing via ISDN. They are now adding in a second site off of the one controller, with a new number range, but that is being delivered over a SIP trunk.
Now, the two sites will be tenanted, but I am struggling with an idea as to how to split ARS out so that site 1 uses the ISDN for outbound, and site 2 uses SIP for outbound.
The problem is that you can't tenant the SIP trunk, so my only idea is that you block access to the ISDN trunks for tenant 2, and then use an ARS list to have ISDN first, and then SIP second. This in theory would allow tenant 1 to access ISDN, and then tenant 2 would get blocked on the first list option, and fail to the second. Any ideas if this will work, or anyone experienced this and have any other suggestions?
