Some IP phones (SNOM 820/870) do not support video calls but are able to download and
display JGEG snapshots from the predefined IP address during a call. The2N IPintercoms do
support this function: set the parameters in this tab.
JPEG Video Activated by Call– enable camera snapshot downloading by Snom 820/870
phones during a call.
JPEG Video Frame Rate– set the frame rate or time periods for camera snapshot
downloading by Snom 820/870 phones.
Multicast
The2N IPintercoms allow you to stream audio signals (from the microphone or another
intercom audio input) via RTP packets sent to the multicast address and receive audio streams
in the same format and play them via the integrated speaker or another intercom audio output.
The audio stream is encoded by G.711 u-law.
Multicast Receiver Enabled– enable receiving of RTP packets on the selected multicast
address and port. The audio stream received is played during an active call too and the
sounds from the two sources get mixed.
Receive Address– set the multicast IP address to receive multicast RTP packets.
Receive Port– set the local port to receive multicast RTP packets.
Volume– set the received audio stream playing volume.
Codec–set the audio codec for RTP packet decoding: PCMU, PCMA, G.722, L.16. The G.722
and L16 broadband codecs are available in selected intercom models only.
