Multiple Call Appearances
You can enable each registered line to support multiple concurrent calls. For example, you can place one call on
hold, switch to another call on the same registered line, and have both calls displayed.
You can set the maximum number of concurrent calls per line key on all-lines basis or a per-line basis. For
example, if you specify 3 concurrent-calls for account 1, you can only have three call appearances on a cor-
responding line key. The additional incoming calls will be rejected.
Note: The number of concurrent calls applies to all line keys. For example, if three line keys are associated with an account,
you can have three call appearances per line key.
