BusinessPhone – Dialog 4223 Professional / Dialog 3213

## Useful Hints

### Connections between external lines

With your BusinessPhone PBX, you can establish an external call diversion or a Conference with more than one external party or transfer an external call to another external destination (e.g. a mobile phone). These features are very useful for everyday business life.

Note:

When these features are used, your BusinessPhone will occupy at least two external lines.

However, there may be disadvantages in connecting to several external lines. We would therefore like to draw your attention to the following:

- Please do not transfer external calls to an external Mailbox, to information systems or to external parties before they have answered.
- Cancel your calls by pressing the Clear key.

If the external parties are not persons (mailbox, automated information or attendant systems, etc.), connections on external lines can last a long time, which can be costly. Moreover, such calls may occupy two of your system’s external lines. You can restrict connections between the external lines by re-programming your system.

Please ask your system administrator or contact our service center for more information.
