Configuration Menu: Extensions
Here you define whether signalling the call number at the analogue extension should
be carried out via DTMF or FSK. In German-speaking countries, FSK is normally u-
sed. For relevant information, please refer to the User's Manual of your analogue te-
lephones.
Internal ring pattern
In this menu, it is set whether or not the ringing signal sequence for internal calls at
the analogue extensions should be different from that of incoming external calls. The
external call rhythm is "1sec. ringing / 4 sec. pause".
