Both programs use the Session Initiation Protocol for VoIP call signalisation. Calls are supported via server-based infrastructure or direct IP to IP. Media streams are transmitted via the Real-time Transport Protocol which may be encrypted with the Secure Real-time Transport Protocol (SRTP) and the ZRTP security protocols. Phoner provides as well an interface for configuring and using all supplementary ISDN services provided via CAPI and thus needs an ISDN terminal adapter hardware installed in the computer.

Both programs support IPv4 and IPv6 connections by using UDP, TCP and TLS.
