We currently have two phone lines and I would like to get rid of the second one but keep the number and port it to a VOIP service. It won't be used all that much so I was thinking the cheapest way to do it would be to use SIPgate as they don't charge a monthly fee (I think).
I was going to buy an ATA from eBay and I wondered about the possibility of using the same SIP account from different ATAs. Is it possible to have two ATAs connected to the same SIP account? Would the phone ring at both locations for an incoming call? Could I make calls from both ATAs at the same time through the one SIP account? Presumably when I make a VOIP call to a UK landline number the caller ID at the recieving end will show my ported number?
Lots of questions!
