Prerequisites
To configure WebEx in Cisco VCS or Expressway, the following are required:
n
Cisco TelePresence Video Communication Server (Cisco VCS) must be running firmware X7.2.3 or a later
release.
release.
n
Note: Customers using Static NAT on VCS Expressway X7.2.3 are highly recommended to not upgrade
to X8.1 or X8.2 due to a defect that will cause the media part of a call to fail. If you are already using Static
NAT with X8.1 or X8.2, refer to the recommended workarounds in

n
Endpoints in the network are registered to Cisco VCS Control or Expressway and/or Unified CM
Note: If endpoints are registered to Unified CM, you must configure a SIP trunk between Unified CM and
Cisco VCS Control. For more information, refer to
Cisco VCS Control. For more information, refer to

n
Cisco VCS Expressway must be assigned a static IP address
n
Firewall must have port 5061 open to allow access to Cisco VCS Expressway
l
If this port is not configured correctly, calls will not take place correctly.

IMPORTANT: Stateful packet inspection used in Check Point Software Technologies, Inc. firewalls is
incompatible with Cisco VCS Expressway and Expressway-E.

l
As a result, it is highly recommended to disable SIP and H.323 application layer gateways on
routers/firewalls carrying network traffic to or from a VCS Expressway or Expressway-E, because,
when these are enabled they can negatively affect the built-in firewall/NAT traversal functionality of the
VCS
