Appendix D. GSM Group Mode
The GSM Group mode is designed to simulate the function of one GSM number with multiple lines. The idea
is to form a GSM group with one number being the "Server". Only this GSM number is announced to the
public. Calls to this number are forwarded to other GSM numbers ("Clients") in the group until all GSM
channels are used up. Effectively speaking, if there are 40 GSM channels in a group, a maximum of 40
concurrent calls can be achieved by just calling the GSM number of the Server channel. The diagram below
demonstrates this concept with only single channel GoIPs. In fact, GoIP with multiple channels can also be
used. Only one "Server" in a group and all the other channels must be set to "Client" individually.
