Is the VOIPo provided adapter accessible to the customer, or locked? I have a VOIP service based on a privately owned Asterisk server that would be convenient to use on Line 2 of the VOIPo provided adapter after I port my main home number to VOIPo. Otherwise I can use my own adapter and just load VOIPo's SIP credentials on one of its lines--or use 2 adapters.

I'll confess, I don't really understand the utility of the included "free second line" unless you use a 2-line phone and plug it into Lines 1 and 2 of the adapter. I have a 2-line phone but use Line 2 for the previously mentioned SIP server, which is what I would like to do with VOIPo's adapter. Thanks for your help.
