In a zonal partitioned system, EP provides the means to allocate telephony licenses to zones manually.
The total number of ports configured for all zones should not exceed the total number of configured telephony licenses allocated to the entire system. When the total number of configured telephony licenses for the entire system falls below the number configured for all zones, the allocation per zone is proportionately adjusted to meet the lower system configuration. Any newly added licenses to the system are not automatically distributed to the zones but must be manually assigned.
 | Note: |
|
Licenses are allocated to a zone for H.323 and SIP. |
Licenses are assigned to a zone and are not moved between zones unless the total number of available licenses drops below the capacity defined for all zones. Here the number of licenses is less in proportion to the licenses assigned to each zone. Excess WebLM licenses are not used when the licenses exceed the capacity of the zones.
Rounding errors are distributed to the zones in the following order:
The remaining licenses are randomly distributed to zones with equal priorities.
Telephony and Announcement Only licenses are taken from WebLM and the licenses are divided between SIP and H.323 in proportion to the number of SIP ports and H.323 stations configured.
<WebLM
Licenses allocated for SIP>= Licenses x (SIP ÷ (SIP + H323))
Where:
Licenses = Total WebLM Licenses (Telephony + Announcement Only)
SIP = Maximum Simultaneous Calls (SIP configuration)
H323 = Total Number of H.323 stations configured
H.323 stations are assigned for applications within organizations through CM hunt groups or vectors. Port groups are configured through EP Administration pages to associated stations to a specific hunt group that becomes associated with a particular application through a pilot number. The application is assigned to an organization through EP configuration web pages.
WebLM SIP licenses can be assigned to organizations, taken from the organizational license pool, and assigned to specific applications within organizations. There are two types of organizations:
Default Organization – The “Default Organization” is not configured and represents applications that are not owned by an organization. This allows applications to be managed with the exception that resource usage by an application is supported. There can be only one default organization that initially has no licenses allocated but which can be configured. Any licenses assigned to the default organization are taken from the Global Common Licenses pool called WebLM Licenses (SIP).
Configured Organization (Organization A & B) – A “Configured Organization” is created and edited through the Administration web pages. Licenses are assigned to organizations through the Administration web pages. Any licenses assigned to the organization are taken from the Global Common Licenses pool [WebLM Licenses (SIP)].
There are two license types for applications:
Guaranteed Licenses – These are licenses which only the application can use and are not given to any other application. Applications are assigned guaranteed licenses from the pool of licenses assigned to a Configured organization or from the Default organization depending on where the application is configured. Applications can be configured with no guaranteed licenses and can be starved by other applications as the common licenses become exhausted.
Common Licenses – These licenses are shared by all the applications after exhausting the guaranteed licenses. The guaranteed licenses are distributed across the media servers.It is possible for the guaranteed licenses to be exhausted on a media server forcing common licenses used to run the application when another media servers still have guaranteed licenses available for the application.
