With what I am trying to do I need 5 services, but the OBi202 only supports 4.
What I would like to do would look like this:
SP1- GoogleVoice Account 1 - for outbound calls (line 1)
SP2- CallCentric Account 1 - For inbound calls with Caller ID name (line 1)
SP3- GoogleVoice Account 2 - for outbound calls (line 2)
SP4- CallCentric Account 2 - For inbound calls with Caller ID name (line 2)
SP5- Anveo E911 (lines 1 and 2)
Why not just use CallCentric for your e911?
When I purchased the e911 service I did not have a CC account. After I got a CC account, I did not even think about their e911 service. I have now looked at both, and CC does not appear to offer an e911 service that will text and email you if the service is used. I would really like to be notified if my wife or kids has an emergency while I am away from the house. If CC offered that level of service, I would probably switch. Good idea.
You can probably accomplish this by configuring your Anveo 911 calls to use vg1 (Voice Gateway 1). You'll need to manually update your configuration to force 911 (and 933 for testing) calls through vg1.
There are various discussions in these forums about using the Voice Gateways for outgoing (only) SIP calls, here is one with some good info

Just be sure to test your configuration well (using 933) -- Good Luck!
