Hello All. Currently I have two voice gateways with T1 PRI VWICs in each gateway. We have two campuses and each gateway services a campus. I have a bunch of route patterns which are duplicated for each gateway. Basically this means that to dial a 215 area code number, I have a route pattern to send the calls out one gateway and a route pattern to send calls out of the other gateway depending on what calling search space the dialing phone or device has.
I'm adding a third gateway loaded with VIC-2FXO cards with POTS lines hooked to it. I want to use this gateway to send 911 calls to the PSTN to better identify the calling location. However, I also need the ability to send a 911 call through one of the other gateways in the event that the POTS line is not able to handle the call for any reason.
I assumed I need to go with a Route Group with the POTS enabled gateway listed first, followed by the PRI enabled gateway. The problem I'm having is, if there are any existing route patterns being used by a gateway, that gateway will not appear in the available devices section of the route group config page. Do I have to rip out all of my current route patterns and rebuild them all with route groups or is there a better way to do this? Thanks
