60 Administering Avaya Video Conferencing Solution 6.0.1 Issue 2.1 April 15, 2011
Note:
Note: The actual settings in this page and find out the customer’s reasons/requirements
for these options to be disabled. Video endpoints do not need to be shuffled to
resume video. Third-party endpoints will support basic call setup only.
4. On the IP Network Region screen, ensure all regions used by video endpoints are
configured correctly.
H.323 SECURITY PROFILES must contain any-auth for Polycom VSX/HDX series devices
to authenticate. challenge is used by Avaya IP Softphone & Avaya one-X
®
Communicator.
pin-eke is used by Polycom VSX/HDX series devices. any-auth encompasses both
challenge and pin-eke.
5. Configure the IP Codec Set screen.
Review all codec-sets used across the enterprise including the codec-sets used by media
processors, trunks, and stations as well as inter-region codec sets. Has the enterprise
selected a single version of G.711 across all Communication Manager servers globally?
Note:
Note: Simplify the codec-set administration by selecting one variant of G.711 across the
entire network of Communication Manager servers. A single variant can be used
globally. Otherwise expect codec mismatch errors and call drops between
Communication Manager servers. Multimedia signaling uses H.245, which is
more sensitive to codec administration than audio-only repeat-fast start signaling.
6. Ensure the intra-region audio administration correct on the IP Codec Set screen.
Review all IP codec-sets used across the enterprise including the IP codec-sets used by
media processors, IP trunks, and IP stations. Wide-band codecs (for example, SIREN
series, G.722.1 series, and G.722-64k) should appear first and are supported for shuffled
Polycom VSX calls only across a single Communication Manager. G.711 should appear
next. Then follow with G.729/G.729A codec, etc.
7. Ensure the inter-region audio administration is correct on the IP Codec Set screen.
Review all codec-sets used across the enterprise including the codec-sets used by media
processors, IP trunks, and IP stations. If there are no bandwidth issues, re-use the codec
set also in use for intra-region. If there are bandwidth issues, specify a low bandwidth codec
first followed by one G.711 codec. If there are severe bandwidth issues, customers can
choose to leave out G.711 and also ensure video is disabled.
8. Ensure the audio administration for Polycom VSXs correct on the IP Codec Set screen.
Review all codec-sets used across the enterprise including the codec-sets used by media
processors, trunks, and stations. If codec-sets used for stations include G.729, then a new
network-region and codec must be defined for use by Polycom VSXs. VSX stations do not
support G.729 but do support G.729A.
Note:
Note: Media encryption is not supported by VSX stations.
9. Ensure the video administration correct on the IP Codec Set screen.
