Configuring B2Bua Transcoders - Cisco TelePresence Administrator's Manual

Field Description
Pattern type The way in which the Pattern string must match
either the source or destination alias of the call.
Exact: the entire string must exactly match the
alias character for character.
Prefix: the string must appear at the beginning of
the alias.
Suffix: the string must appear at the end of the
alias.
Regex: treats the string as a
Pattern string The pattern against which the alias is compared.
Action The action to take if the source or destination
alias of the call matches this policy rule.
Allow: the call can connect via the transcoder.
Deny: the call can connect but it will not use
transcoder resources.
State Indicates if the rule is enabled or not.

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.

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).
When you are making or testing
configuration changes to your transcoder
policy rules, you may want to temporarily
enable or disable certain rules. You may
also want to configure certain rules but only
apply them occasionally. You can do this by
selecting the rule's check box and clicking
Enable or Disable as appropriate. Any
disabled rules still appear in the rules list
but are ignored by the B2BUA when
determining which calls are routed via the
transcoder.
