Telephone Add-On
The video system has a built in audio bridge* that can bring in Voice
over IP (VoIP) telephony or normal telephone sites using ISDN.
A built in audio bridge is an audio MCU (Multipoint Conference Unit).
Note that this requires a system with mixed audio output (audio
from local and far end) and one audio input without integrated echo
cancelling.
In addition to using ISDN and IP for your telephone sites, it is possible
to connect a telephone using normal POTS line** by:
Connect the audio out from the conference telephone to the AUX
input.
Connect the audio input from the conference telephone to the AUX
output, which provides a mixed signal between local and far end.
* Optional MultiSite package available
** Require a conference phone with external audio input and output
