exchanges (PULSE). . Page 40
Temporary tone dialling

ling when a connection has already been made.

Prefix dialling
This function enables a specified number to be dialled automatically prior to the actual
phone number. This is mainly implemented when using call−by−call numbers.
A call−by−call prefix with up to 24 digits can be stored. The call−by−call number is auto-
matically prefixed and is not displayed in addition to the selected phone number.
If you press the Call button first to obtain a dialling tone and then enter the phone num-
ber, the call−by−call number stored is also prefixed.
