Phoner 3.23

This application enables voice connections to landline , cellular network and VoIP .Phoner can be used as softphone on stationary and mobile computer devices attached to analogue or digital (ISDN) subscriber lines and as SIP client.

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.
