calls that invoke the B2BUA to apply a media encryption policy or for ICE messaging support
Note that for calls via the Microsoft interoperability service, the B2BUA application always takes the media but the
call is not classified as a VCS traversal call and does not consume a traversal call license (it may still consume a non-
traversal license if the VCS takes the call signaling).
call is not classified as a VCS traversal call and does not consume a traversal call license (it may still consume a non-
traversal license if the VCS takes the call signaling).
Traversal calls use more resource than non-traversal calls, and the numbers of each type of call are licensed
separately. The VCS has one license for the maximum number of concurrent traversal calls it can take, and another
for the maximum number of concurrent non-traversal calls. You can increase the number of each type of call
available on your VCS (or VCS cluster, see
separately. The VCS has one license for the maximum number of concurrent traversal calls it can take, and another
for the maximum number of concurrent non-traversal calls. You can increase the number of each type of call
available on your VCS (or VCS cluster, see
for more information) by
purchasing and installing the appropriate option key. While every deployment is different, as a guideline we
recommend that your system has a 10:1 ratio of registrations to concurrent call licenses.

Note that a non-traversal call on a VCS Expressway will consume a traversal license if there are no non-traversal call
licenses available (in this situation, the call will remain a non-traversal call — the VCS Expressway will not take the
media, even though it is using a traversal license).

License Bypass for Calls to Collaboration Meeting Rooms (CMRs)
The VCS no longer requires traversal call licenses for calls to and from cloud-based CMRs. This includes SIP calls
between Collaboration Cloud and the CMR Hybrid solution.
between Collaboration Cloud and the CMR Hybrid solution.
Note:
This only applies when the dialed string does not need transformation on the VCS (for example,
user@sitename.webex.com).
Although untransformed SIP calls to cloud-based CMRs do not consume licenses, they do consume resources and
may not progress if the VCS is at full capacity.
may not progress if the VCS is at full capacity.
There is no license bypass for CMR Premises calls. H.323 calls to cloud-based CMRs still consume licenses.
