I'm a bit confused on many of the free DID services.
I have a DID in Canada so my kid can use my Obi like a calling card via AA, and I have a DID in UK so our family can call local number there that rings here. I use
voip.ms and pay about $10.00 for both DID's and they are just incomming only.
I see many free DID's out there and am wondering if I should instead be using them? My Canadian DID I'm paying $5.95 a month for and only use for incoming - should I instead look for a free Canadian DID?
