Enabling registrations and calls 

SIP endpoints register SIP URI (Uniform Resource Identifier) addresses to the Cisco VCS. 

SIP URIs are made up of the user information @ domain name (for which the Cisco VCS has 
authority). 

The domain name must be configured on the Cisco VCS to allow SIP endpoint to register, using the 
domain name as part of the URI. 

To configure a SIP domain: 
1.  Go to the Domains page (VCS configuration > Protocols > SIP > Domains). 

2. Click 

New. 

3.  Enter the domain name into the Name field.  

4. Click 

Create domain. 

5. The 

Domains page will display all configured SIP domain names. 

 

 

 

Note: After the domain name has been configured (on the Cisco VCS), SIP endpoints will be able to 
register using this domain name, for example: a Cisco VCS is configured with the domain name of 
example.com will accept registrations from an endpoint registering using SIP URI of 
user1@example.com. 

Note: After SIP endpoints have registered, they can make and receive calls using their SIP URIs.
