Which Telephone Adapter Should I use

[otacon6530]

I just recently bought a WorldACCXX TA-200 Telephone Adapter and have not been able to get the sip to work with magicjack services.

I do not want to go out blindly to find and find myself getting another Adapter that does not work with Magicjack.

Could some one list some that are cheap and that they know works with magicjack services and which do not?

Works:
1. none

Does not Work
1. WorldACCXX TA-200
