Informacast

The

intercoms support the audio streaming Informacast protocol, which

2N Helios IP

helps you set up an audio stream (unicast/multicast RTP/UDP encoded with G.711
U-law) between the intercom and an Informacast server or any other Informacast
client.

When you enable this service, the Informacast servers are found automatically in the
LAN via the SLP and the intercom gets registered with them automatically. The
Informacast server with which the intercom is registered can send the audio stream
setting up commands to the intercom.

Broadcast - the intercom receives audio from the Informacast server and plays

it via an integrated speaker.
Capture - the intercom records audio via an internal microphone and sends it to
the Informacast server.
Listen - the intercom receives audio from another Informacast client.
