If dual stream (BFCP) does not work:
Enable BFCP on SIP profile for
endpoints in CUCM.
Enable BFCP for SIP trunk profile if
calling to/from a Cisco VCS.
NTP: Configure Unicast NTP references
for endpoints in CUCM.
Provisioning: Make sure the endpoint has
a DNS server that can resolve the host
name, or change CUCM > System >
Server, to be IP address instead of
hostname.
CSCug19308: CUCM 8.6.2 directory
returns more than the corporate limit set
by the endpoint in the search. Fixed in
CUCM 9.0
To get the correct call back number in call
history for trunk calls between VCS and
CUCM, make sure Directory URI´s are
used on every endpoint and that a top
level domain is specified in the Enterprise
Parameters of the CUCM. Otherwise
endpoints will show DN@CUCM_IP in
history instead of URI@domain.

If you configure a trunk towards CUCM 8.6 or
9.0, you must create a custom SIP trunk that
does not remove BFCP lines towards CUCM. If
you choose CUCM as profile in the VCS, BFCP
will be removed and dual stream (BFCP) will
not be possible between CUCM and VCS.
