New Polycom HDX video conferencing systems have been installed
in HSB 132 and BRK180G. Classrooms UHB 3080 and BRK 141A will also have
upgraded Polycom HDX video conferencing systems by the end of the week.
These systems will retain their existing H.323 public IP addresses to receive
calls from outside video conferencing systems. All four Polycom video
conferencing systems are registered via SIP with the campus MS Lync server,
which means they can make and receive calls from MS Lync clients. Below is
a picture of a video call from a Lync client to the HSB 132 Polycom system.
In order to make a video call from Lync to the Polycom systems
you need to search for their service accounts in Lync. The service
HSB132VC (HSB 132 HDX 6000 Video Conferencing)
BRK180GVC (BRK 180 HDX 7000 Video Conferencing)
BRK141AVC (BRK 141A HDX 8000 Video Conferencing)
UHB3080VC (UHB 3080 HDX 8000 Video Conferencing)
After you find the service accounts in Lync (See below) you can
connect to them by right clicking the Lync service account and clicking on Start
a Video Call. All four systems are configured to auto answer point
to point calls.
The nice thing about this is that with the Lync client and an
internet connection you can join a video conference from anywhere. You
don’t have to be on campus to join. The supported bandwidth ranges for
each resolution available in the Microsoft RTV codec are CIF (352×288 50 – 250
Kbps), VGA (640×480 350 – 600 Kbps) and HD (720p) (1280×720 800 – 1500 Kbps.)
A quad-core processor is required on the Lync client’s computer
in order to support both sending and receiving of 720p high definition video for
two-party calls. Without a quad-core processor, the video on the Lync client’s
computer will be either CIF or VGA.
The campus Lync server supports multiparty video conferences via
it’s Lync AV Multipoint Control Unit (MCU). The maximum resolution size of
the Lync AVMCU is VGA (640 * 480).
The Polycom system in BRK 180G has a 4-way Multipoint Processor
Plus license which enables it to have a 4 port bridge capability.
The campus MS Lync server uses the
email@example.com as the sip address when
accounts are enabled. Therefore, to call a Lync user from the Polycom’s
simply type their email (see below)
You can also call a Lync user from the Polycom’s by going to
Directory/UISAD Directory and searching for the user (See below)
Another feature is the ability to create a new Lync Online
Meeting on Outlook and invite the Polycom service accounts.
On the HDX Polycom systems you can go to the Calendar under
System/Utilities/Calendar to see and join Online Meeting invitations.
The Polycom HDX systems can share desktop content. The computer input content
is pushed to the video conference using the H.239 protocol or Polycom
People+Content by connecting a laptop/PC via DVI cable to the Polycom units.
Unfortunately, at this time it is not possible to share content from the MS Lync
client’s desktop to the Polycom.
The Polycom HDX systems are operated using a remote control. The picture
below shows how to use the Polycom HDX remote control.
