Configuring Basic Features

Multiple Call Appearances
You can enable each registered line on the phone 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 display.
You can set the maximum number of concurrent calls per line key on a phone or a per-line basis.
For example, if you configure the maximum number of concurrent calls per line key for account
1 to three, you can only have three call appearances on line 1. The additional incoming calls will
be rejected. If you assign a registered line to multiple line keys (refer to Multiple Line Keys per
Account), the number of concurrent calls applies to all line keys. That is, you can have three call
appearances per line key.
Procedure
Multiple call appearances can be configured using the configuration files.
