7.5. Incoming calls from GSM to VoIP network
Incoming calls from the GSM network are subjected to the
algorithm described in Fig. 24 and the following steps:
An incoming call is handled depending on how the parameter
“Mode” is set in the table “GSM incoming groups”. Here it is
possible to set several possibilities:
• Reject / Ignore of incoming calls – incoming calls will not be
routed to the VoIP network. On the side of the GSM network a
request for connection can either be rejected or ignored (the
caller ringing tone)
• Report to PC – information about an incoming call is sent to a
PC with a servicing program. The caller is then played an
announcement or dial tone. The servicing program then ensures
the remaining routing of the call.
• If none of the above possibilities is set, an enquiry is made as
to whether the function Callback is activated. If for incoming
calls the function Callback is activated, the callback table is
searched. If the callback function is not permitted for the given
CLIP (CLIP is not contained in the table Callback), the call is
either refused or ignored depending on the setting in the menu
GSM incoming groups. If the table does contain the CLIP,
VoiceBlue waits for the end of the call from the GSM
subscriber and then calls back to the subscriber in the GSM
network.
• If the function Callback is not active or callback has already
been performed, a test is conducted for the permission of the
service Mobility extension.
• If the service Mobility extension is permitted, the caller is
played the list of announcements Mess 1, Mess 2 and Mess3
(see chapter 6.4). The subscriber may then either activate or
deactivate the function “Follow me” and “SMS at no answer”
or transfer the selection to the subscriber in the VoIP network.
After the connecting of a call it is possible, as a result of the
function, to hold the call, forward it or terminate it as described
in chapter 6.3.
