SIP is the most used protocol for establishing voice calls over IP connections. By supporting SIP, Phoner can contact a wide range of peers like Asterisk and countless VoIP providers. The advantage is, that only a functional Internet connection is required.
If the PC is connected to a PBX or PSTN with an ISDN terminal adapter , all supplementary services supported by CAPI can used. The PC then acts like a normal ISDN phone. CAPI drivers will be provided by the manufacturer of the ISDN hardware.
TAPI is a generic interface for all kinds of communication hardware. It can be a PBX,a telephone or a built-in PC hardware. This wide range of possibilities can have disadvantages on the other side. This is the reason why TAPI development was stopped in Phoner.
