SIP - Groundwire is a SIP Client, not a VoIP service. You must have service with a VoIP provider or PBX that supports use on a standard SIP client to use it.
VoIP over 3G - Be aware that some mobile network operators prohibit or restrict the use of VoIP over their network. They may prohibit the use of VoIP or impose additional fees and/or charges when using VoIP over their network.
