Receiving calls to a MultiSite
When the MultiSite receives incoming calls you can accept or reject it. Pressing the green key
is equivalent to pressing Accept. Pressing the red key is equivalent to pressing Reject.
End a MultiSite Call
Ending a MultiSite Call is not very different from ending a normal point-to-point call. Use the
red key on the remote control or End Call from the main menu. The end call menu lists all the
calls that participate in the conference. To end a single call, select the call, press OK or the
red key on the remote control. To end all calls, press the End All Calls button in the menu.
Duo Video in MultiSite calls
In a MultiSite call, the MultiSite can transmit the Duo Video and/or H.329 to the other
participants that support Duo Video and/or H.329. This means that any participant can send
Duo Video and the MultiSite will transmit it to the other participants. The participants that do
not support Duo Video or H.329 will only receive Main Video.
Bandwidth for MultiSite calls
If the MultiSite system does not have enough bandwidth to add another site, the system will
automatically downspeed to allow an additional site to be added to the conference. Be aware
of that Far End must support downspeeding and must have enough bandwidth.
Downspeeding can be time consuming. In order to optimize connection time, use low
bandwidth in the first call.
Example: The system has 512 kbps available and you want to connect 3 sites in addition
to the host.
1. Begin the first call with Auto. As you add more participants with Auto Call Settings,
bandwidths will downspeed. This is the simplest way to establish a MultiSite call,
but downspeeding will lengthen the connection time.
2. To save time, specify 128 kbps for the calls. The system will end up with 4x128
kbps = 512 kbps.
The video calls in a conference do not have to use the same bandwidth. If you have
enough bandwidth available, you can use 128 kbps on one call, while 384 kbps or any
other bandwidth on another call in the same MultiSite conference.
MultiSite supports both Voice Switched and Split Screen mode (see chapter 3.12.2 MultiSite
Layout for more about Layouts). The system has Auto Split as default picture mode.
Mix ISDN/LAN
