I have the Zoiper softphone app configured (through a Callcentric IP Freedom account) and know how to use it to make outgoing calls from Zoiper, via the OBI attendant). What I don't know (or cannot remember) how to do is to make calls that can be received by the Zoiper softphone. I have tried calling the callcentric number directly (with and without extensions) and that doesn't work. I wanted to try to call the Zoiper extension from the obi attendant but I don't know how to access the attendant from my OBI attached phone. Any help is appreciated.
