Usage tips
This feature only applies if FindMe is
enabled.
Note that Lync only allows FindMe users
to register if the FindMe ID being
registered is a valid user in the Lync
Active Directory (in the same way that
Lync users can only register if they have a
valid account enabled in the Lync AD).
Only FindMe names with this domain will
SIP be registered to Lync.
You should enable this option if you need
to use a transcoder such as the Cisco
TelePresence Advanced Media Gateway
to transcode between standard codecs
(such as H.264) and Microsoft RT Video
and RT Audio.
All transcoder communications are carried
out over TLS.
If Enable transcoders for this B2BUA is
Yes, then all calls are routed via the
transcoders by default.
If transcoder resources need to be
reserved for specific types of calls, you
can use this option to limit the types of
calls that are routed via the transcoders.
Set this option to Yes and then define the
required policy rules.
This is recommended for calls traversing a
Microsoft Lync Edge server.

TURN servers, click Configure B2BUA
