To use BFCP with endpoints registered to CUCM 8.6.1 or later, select Custom for the Advanced
Zone profile, configure the entries as above, then change SIP UDP/BFCP filter mode to Off.
Zone profile, configure the entries as above, then change SIP UDP/BFCP filter mode to Off.
Further configuration will be needed on CUCM – see ”Appendix 12 – Enabling BFCP”.
If TLS connectivity is used from Cisco VCS to CUCM, and VCS is configured with optimal routing,
either CUCM has to trust the certificates for all VCSs in the network, or, select Custom for the
Advanced Zone profile, configure the entries as above, then change Call signaling routed mode to
Always. This ensures that the VCS neighbored to CUCM will remain in the call signaling path for calls
to and from CUCM, so that CUCM only has to trust this VCS cluster’s certificates.

Call signaling routed mode set to Always is also important where endpoints are using GRUU contact
addresses (from VCS X7.0) or where IP addresses of video devices are unroutable directly from
CUCM. It is should also be set when interfacing between CUCM and MCUs for Multiway. VCS staying
in the signaling path ensures messaging can be routed properly.
