Required Administration
Before administering any video endpoints on your system, you must perform the following
procedures:
● configure IP codec sets
● configure IP network regions
Configure IP Codec Sets
To configure the IP codec sets that you want to use for video:
1. Use the change ip-codec-set x command (where x is the chosen IP codec set) to access
the IP Codec Set form.
2. Define the codecs. The following codecs are recommended:
● SIREN14-48K (1 fpp, 20 ms)
SIREN14-48K are wideband codecs. Since most Polycom systems are not configured for
stereo, it is not recommended to use a stereo SIREN codec as a default.
● G.722-64K (2fpp, 20 ms)
G.722-64K are wideband codecs. These codecs allow wideband with video endpoints
that do not support SIREN codecs. G.722-64K codecs are required if you are using VSX
systems in mixed H.320/H.323 environments. Be sure to place this codec above the
other non-Siren audio codecs.
● G.722.1-32K (1 fpp, 20 ms)
G.722.1-32K are wideband codecs. These codecs allow wideband with video endpoints
that do not support SIREN codecs.
● G.729A (no silence suppression, 2 fpp, 20 ms)
Polycom systems do not support all variants of G.729 codecs. If you want to use G.729,
you must specify G.729A. If you specify G.729, no audio problems arise. All variants of
G.729 codecs are narrowband codecs.
Note:
Note: Keep in mind the following information:
- Wideband codecs should appear before narrowband codecs in the codec set. If you
are using VSX systems in mixed H.320/H.323 environments, place the G.722-64K
audio codec above the other non-Siren audio codecs.
- G.711 codecs are recommended for Avaya Meeting Exchange 5.0.1. Avaya
Meeting Exchange 5.0.1 does not support wideband codecs.
