transcoder.
transcoder.
Address
The IP address or Fully Qualified Domain Name
(FQDN) of the transcoder.
(FQDN) of the transcoder.
If you have several transcoders you are
recommended to either use their IP
addresses or to give each device a different
FQDN.
recommended to either use their IP
addresses or to give each device a different
FQDN.
You may encounter problems if you use an
FQDN that resolves to multiple transcoders
(via DNS-based load balancing). This is
because the B2BUA will first use DNS to
discover the number of available ports on a
transcoder, and then use DNS again to route
a call to the transcoder. If the DNS lookup
can resolve to different transcoders there is
no guarantee that the call will be directed to
the same transcoder that provided the
resource information.

Restarting the B2BUA Service
The B2BUA service restart page (Applications > B2BUA > Microsoft Lync > B2BUA service restart) is used to
restart the Lync B2BUA service.

A restart is sometimes required to enable certain configuration changes to the B2BUA to take effect. A system alarm
will be raised if a service restart is necessary.

Note that this function only restarts the B2BUA service; it does not restart the Expressway. However, restarting the
service will cause any active calls being managed by the B2BUA to be lost.

To restart the B2BUA service:

Go to Applications > B2BUA > Microsoft Lync > B2BUA service restart.
2.
Check the number of active calls currently in place.

Clustered Expressway systems
On a clustered Expressway you have to restart the Lync B2BUA service on every peer. You are recommended to
ensure the service is configured and running correctly on the primary peer before restarting the B2BUA service on the
other peers.
