Re: Looking for good ATA (VOIP) Locked is the exact same idea as a cell phone. You buy (or are given it) it from a company, and can only use it with that specific company.
Unlocked means you are free to use it with anyone you chose.
If you buy the SPA112 or SPA122 from a place like Canada Computers it will most certainly be unlocked. If you buy it from Fleabay or Kijiji you're taking the word of the seller as true.
