Starting a group call
A group call is a semi-duplex voice connection. While one subscriber speaks, all
other subscribers in that group listen to this call. After that, the other subscribers can
answer the call, one after the other.
Prerequisite:

The channel is not occupied by a call.

The connection with the subscribers in the called group is set up. The display
shows the name or the call number of the group (GSSI).
After a short time, your speaking enable signal is transmitted unless another
subscriber is transmitting. The display additionally shows your name or your call
number (ISSI).
