Cisco VCS - System has reached resource limit.

Hi All,

On the VCS, Conference not able to establish a call via sip and e1 gateway and unable to schedule or book a conference (error No Resource available) What could be the cause of the issue? Please see attached image. Thank you

The "System Has Reached Resource Limit" alarm could be a number of things, such as:

• number of registrations
• number of non-traversal calls
• number of traversal calls

That any one of those licenses on the VCS may be used and none are available.  If you log into the VCS web interface, on the overview page you can see it's resource usage, as well as details about the alarm.  In your case, it sounds as if either none of the non-traversal or traversal call licenses are available, so calls are unable to connect.

What is the resource usage for the non-traversal and traversal calls on the VCS, and how many of each license type do you have installed?

How many endpoints are in an active call at one time?
