Create and import large numbers of extensions
There are limitations on the number of extensions you can assign to an IP Extension Pool Member Group or to an IP Recorder.
-
You can assign a maximum of 20,000 extensions to a Member Group or to a single Recorder. This is the default limit. If you need to assign more than this number, contact the supplier of your Recorder.
Example: Member Group A has 5,000 extensions. Member Group B has 18,000 extensions. You cannot assign both of these Member Groups to one IP Recorder, because the total number of extensions assigned to this Recorder will be 23,000, and the maximum is 20,000.
This rule applies when clustering or assigning new phones to Member Groups in a cluster. For example, if the total number of extensions belonging to all the Member Groups in a cluster exceeds 20,000, the operation will fail (an error message will indicate this).
-
You cannot create a range of more than 5,000 extensions at a time.
Example: To create 10,000 extensions using the Create Range option, you must create the range 1 to 4,999, and then another range from 5,000 to 9,999. The same rule applies when unassigning phones from an IP Member Group: you must unassign in groups of 5,000.
-
You can assign duplicate extensions to a Recorder within a single Data Source, through Member Group association (that is, you can have the same extension number in different Member Groups).
Example: Assume you have Data Sources named DS1 and DS2. Assume also that you have two Member Groups, MG1 and MG2:
-
MG1-DS1 can be assigned with extension 1-10 in Data Source DS1
-
MG1-DS2 can be assigned with extension 4-6 in Data Source DS2
-
MG2-DS1 can be assigned with extension 5-8 in Data Source DS1
-
-
You cannot have duplicate extensions across data sources.
Example: You cannot associate the Member Groups MG1-DS1 and MG1-DS2 (above) to a Recorder, because this would cause duplicate extensions (4 - 6) across Data Sources.
These extensions include primary and secondary extensions. For example, if a phone has one primary and five secondary extensions, the total extensions considered for calculation is six.
