Cisco VCS peers
Cisco VCS peers
From CUCM version 8.5, to connect CUCM with a cluster of Cisco VCS peers there are 2 methods of
providing CUCM with the addresses of the VCS cluster peers:
providing CUCM with the addresses of the VCS cluster peers:
the trunk to VCS specifies a list of VCS peers
the trunk to VCS specifies the DNS SRV address for the VCS cluster
Prior to CUCM 8.5, there was only 1 method; the trunk to VCS had to specify the DNS SRV address
for the VCS cluster.
for the VCS cluster.
Configuring the trunk to VCS to specify the DNS SRV address
for the VCS cluster
for the VCS cluster
Ensure that in the DNS server used by CUCM a DNS SRV record exists for the cluster of VCS peers;
in the DNS SRV record each peer should be set with equal priority and equal weight.
in the DNS SRV record each peer should be set with equal priority and equal weight.
