5.4.1 Phone
The Phone service is one of the basic functions of the intercom: helps you establish connections
with other IP network terminal equipment.
The 2N LTE intercoms support the extended SIP and
are compatible with and certified by the leading SIP PBX and terminal equipment manufacturers
(CISCO, Avaya, Broadsoft, etc.).
The intercom supports up to five parallel calls: 1 outgoing and up to 4 incoming calls. Just one of
the calls can
be active – the audio stream is interconnected with the microphone and speaker
and video stream with the camera. The other calls are always inactive – the microphone and
speaker are muted, the intercom receives the DTMF characters for the opponent to control the
intercom (activate/deactivate profiles, users, etc.).
Typically, the intercoms are used for outgoing calls and incoming calls are inactive – the
microphone and speaker are muted. However, you can configure your intercom to make
incoming calls active and ringing; refer to
the Calls tab. Press the * and # keys on the numeric
keypad to answer and terminate an incoming call.
The 2N LTE intercoms use the G.711 , L16 , G.722 and G.729 protocols to encrypt or compress
audio streams and the H.263 or H.264 codecs to compress video streams. Broadband codecs
L16 and G.722 are available in selected 2N LTE intercom models only. Choose your preferential
codecs in the Audio or Video tab.
