This may be too late since this is an old topic but here goes ..

I had a similar situation with the same cable modem but a different Latitude Communicator.  My Latitude box was the old one that had no switches and just the phone jacks.  I tried for weeks to get my device to communicate reliably through a VOIP box and provider, but I never did find anything I could say was a 100% fix.  I was NOT using an OBI by the way.

Anyway, I thought I was going to be locked into my stupid land line phone charges forever until I found on the Boston Scientific website that there is a new Latitude Communicator that connects to your router via a USB ethernet adapter.  The new Latitude Communicator box was free, but the ethernet adapter costs $75.  Which is nothing considering I was paying almost $30 a month + taxes for my phone line.  I did not need doctors approval and it was all handled in one phone call which lasted maybe 10 minutes.

The new box arrived by FedEx in two days and I was up and running in under 5 minutes.  I submitted the $75 charge to my insurance, but I haven't heard back from them yet.

Hopefully you'll see this and maybe get one of the new Latitude boxes to help your situation.
