Configuring the Cisco VCS

This deployment guide assumes that the Cisco VCS is accessible on an IP network and has had a

basic configuration implemented. This means that the Cisco VCS has been configured with:

 IP details

 DNS details

 NTP server details

Note: Brief instructions on how to carry out this configuration is available in ‘Appendix 1 – Basic Cisco

VCS configuration’ on page 18.

If the system is required to support calling to non-registered endpoints, a DNS zone should be

configured together with a search rule that sends any calls to it that are not for the Cisco VCS’s local

SIP domain.

Firewall ports

If the Cisco VCS is placed in a DMZ, to enable SIP calls to be received the following IP ports must be

open to the Cisco VCS through the firewall:

 5060 (if basic SIP connection is required)

 5061 (for SIP over TLS)

 50000 to 52399 (for media)

Check option key
