Jabber Guest licensing and call capacity
The VCS licensing requirements for Jabber Guest sessions are as follows:
n
Each session typically uses 4 TURN server relays on the VCS Expressway.
n
2 traversal call licenses are required per Cisco Jabber Guest session:
l
1 traversal call license on the VCS Expressway for each Cisco Jabber Guest session
l
1 traversal call license on the VCS Control for each Cisco Jabber Guest session
The maximum number of Jabber Guest sessions that can be supported through the VCS depends on the type

Jabber Guest configuration summary
You must configure the VCS with the domain that will support Jabber Guest services, associate that domain
with one or more Jabber Guest servers, and set up the call routing to the destination endpoint.
with one or more Jabber Guest servers, and set up the call routing to the destination endpoint.
In summary, the steps required to configure your VCS system to support Jabber Guest are:
1. Install VCS security certificates and set up a secure traversal zone for Unified Communications between
VCS Control and VCS Expressway.
2. Configure the VCS Expressway:
a. Enable Jabber Guest services.
b. Enable TURN services.
c. Lower the MTU size from 1500 to 1400 bytes.
b. Enable TURN services.
c. Lower the MTU size from 1500 to 1400 bytes.
3. Configure the VCS Control:
a. Enable Jabber Guest services
b. Configure the domain that requires Jabber Guest support
c. Configure Jabber Guest servers and associate their addresses with the domain
d. Set up secure neighbor zones to the Jabber Guest servers
