Solved One ISP, two routers (one managed VoIP) each with a static

Specs: Macintosh
I need to know the best most efficient way to make this work. I have a customer moving from two Comcast broadband modems to one Comcast fiber modem with a single ethernet handoff. Currently the customer has each broadband modem going to separate routers, one for a managed VoIP service (phones only) and the other for their data network (PC's, printers, WAP's, etc.). Basically, two totally separate networks. The customer is moving to Comcast fiber service because they offer better speeds, more stability, etc... The fiber service will have two static IP's, one for each router. The VoIP network router is an Edgewater (old and slow) and the data network router is a Cisco RV340 (new but appears to work well). The reason for the separate networks is the managed VoIP service router will not allow the customer to manage the network the way they want. They have also had numerous occasions that the VoIP router shuts down due to maintenance, updates and such in the middle of the day. Not good. The customer would like to move away from this particular VoIP service but they are under contract for three more years, so thats not an option.

Would the best scenario be the fiber ethernet handoff patched to a small five port gigabit switch, then patch one LAN port to the VoIP router WAN port and patch a second LAN port to data network router WAN port? Each router configured with its specified static IP. Thoughts and opinions appreciated.

I haven't used that router, but can't you just connect the Edgewater to the Cisco and configure the Cisco to forward the Edgewater's traffic?

Is the fiber connection having 2 VLAN's to separate the 2 IP addresses?
In this case a Ethernet-switch with VLAN capability can connect the 2 routers.
Check the configuration of the modem (if any) or ask the ISP for details.

I'd wager they're not using VLAN's and the two IP's are in the same subnet

What Razor2.3 said would be your simplest scenario but may require someone onsite to contact the provider and get their help to configure routing in the Cisco router to ensure the VoIP traffic goes where it needs to.

The customer would like to move away from this particular VoIP service but they are under contract for three more years, so thats not an option

There are always ways to get out of contracts up to and including paying it out. If that's not an option, get the contract out and read the fine print. No decent provider I know of would run updates during the day when it's most likely to disrupt business. If there is anything in the contract stating they will only run disruptive updates during the night, they've breached their contract and you can leave without penalty.

Advise whomever is in charge to ensure (next time around) they have things like that spelled out in the contract before signing it.

Also, you might talk to the provider about new upgraded equipment (something else I would have written into a future contract).

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.

Thanks for the feedback. I have reached out to the VoIP host and they will not provide any information, the ISP is hands off as well. I agree on all points with the contact but I was not involved when the contract was signed. I've asked the customer these questions and more and they are still trying to find the contract so we can reference it. Good grief!! They are a frustrating bunch. Appreciate the assistance.
