R
Repeater
With a repeater you can increase the range of handsets connected to a base
telephone. This device receives the wireless signal of the base telephone and
broadcasts it further.
Ring delay
For each internal party, you can specify how many rings take place before this party
hears the ring. This can also be set for each MSN phone number.
For example, your handset, in addition to the base telephone (which rings on the
first ring) could ring after three rings for the private phone number, and ring on the
first ring for the business phone number.
Ringback when the call is not answered
If a called party does not answer a call, the caller can set up an automatic ringback.
As soon as the destination party has established a connection and is free again, the
caller will get a ringback. This performance feature must be supported by the
telephone exchange. The ringback request is automatically cancelled after
approximately 2 hours (depending on the telephone exchange.
Ringback when the number is busy
First the caller must activate ringback for his end device. A connection is
automatically established as soon as the destination connection is no longer busy.
When the connection is available, the caller is signalled. As soon as the caller picks
up his handset, the connection is established automatically.
