hTELDN

A handle to a directory number structure for the number whose call appearances you want to count.

internalExternal

A constant that specifies where a call appearance originates relative to the local switch or closed user group. The function counts only call appearances that meet the specification you provide here. You can use one of the constants described in "Call Origination Types" (page 4-13).

function result

The number of call appearances that fit the specification in the internalExternal parameter.

DESCRIPTION

The TELCountCAs function counts non-idle call appearances--those whose state is not telCAIdleState--for a given directory number. Typically, you call TELCountCAs at application start-up, in order to learn if any call appearances already exist.
