Configuring B2BUA transcoders
Transcoders are used to convert digital media from one format to another. The only transcoder currently
supported by the B2BUA is the Cisco TelePresence Advanced Media Gateway (Cisco AM GW).
The B2BUA can use the Cisco AM GW to transcode between standard codecs (such as H.264) and
Microsoft RT Video and RT Audio to allow high definition calls between Microsoft Office Communicator
(MOC) clients and Cisco endpoints.

Multiple transcoders can be configured for load balancing purposes; the B2BUA automatically manages

which transcoder to use.
The status of each transcoder is shown, this includes:

whether the transcoder is accessible or not

the number of available connections; note that Cisco AM GW calls require 2 connections per call

to control whether the B2BUA uses transcoder resources and
are used to filter which calls are allowed to be routed through the transcoders.
Usage tips
You can test whether a pattern matches a
particular alias and is transformed in the
expected way by using the
tool
(Maintenance > Tools > Check
pattern).
Use this setting when making or testing
configuration changes, or to temporarily
enable or disable certain rules. Any
disabled rules still appear in the rules list
but are ignored.
