I have used 2 and it rings different on my phone.

I tried a single phone and moved it back and forth between my VOIPo ATA and my current provider's ATA. Line 1 in both cases. No luck on the VOIPo ATA.

I called support and they suggested I create a ticket so it could be forwarded appropriately - I've done this.
