codec; use these options only if you
experience a particular problem when
using a certain codec with the ISDN
gateway. If the IP endpoint is a Cisco
TelePresence MCU or IP VCR,
consider disabling the codec on that
device instead.
IP and ISDN endpoints negotiate
between themselves which video
codecs to use during a call. Use these
options if you wish to restrict the
choices available.
Prohibiting video codecs may prevent
endpoints negotiating a compatible
codec; use these options only if you
experience a particular problem when
using a certain codec with the ISDN
gateway. If the IP endpoint is a Cisco
TelePresence MCU or IP VCR,
consider disabling the codec on that
device instead.
Note that H.263 also encompasses
H.263+.
IP and ISDN endpoints between
themselves negotiate which content
codecs to use during a call. Use these
options if you wish to restrict the
choices available.
Note: The ISDN gateway does not
advertise content at bandwidths of
128kbps or lower. Cisco recommends
a total call bandwidth of at least
384kbps for a video call with content.
Prohibiting content codecs may
prevent endpoints negotiating a
compatible codec; use these options
only if you experience a particular
problem when using a certain codec
with the ISDN gateway. If the IP
endpoint is a Cisco TelePresence
MCU or IP VCR, consider disabling the
codec on that device instead.
Usage tips
The ISDN gateway passes any
floor/chair control requests received. It
does not process them in any way.
