Voice over IP (VoIP)
●
VoIP system telephone’s audio signals are generated by the telephone
itself. DTMF dial tones and Music on Hold are produced by the Media
Gateway function.

A VoIP system telephone can also be operated without a permanent
connection to the communications system, for example via VPN
connection.
●
Signalling data for call control, call data during three-party conferences,
connections to conventional terminals and external connections is
exchanged between the VoIP system telephone and the communications
system. During a call between two VoIP system telephones, call data is
exchanged directly between the two VoIP system telephones.

During the device’s start procedure, the IP address is configured and the
device software is requested via the DHCP and TFTP network protocols.
