The outgoing call is not billed until the called party answers the call.
The GSM network signals the call answering moment and the GSM gateway
transfers this information to the SIP Proxy.
It can be set for GSM outgoing calls that the calling subscriber should be sent the
connection tone* instead of a silence between the request sending to GSM and
the ringing tone.
* This option can be activated for TC35i modules.
Routing Algorithm for Incoming Calls
Incoming calls are processed according to the parameter setting in the Mode GSM
table. The following options are available:incoming groups
Reject/ Ignore incoming calls – incoming calls are not routed to the VoIP
network. On the GSM side, the connection request is either rejected or ignored
(the caller hears the check ringing tone).
If the above mentioned option is not selected, the CLIP routing table is checked.
If the calling number is found, it is checked for CallBack first. If the CallBack
function is enabled for this number, will ignore the2N VoiceBlue Next

AutoDial settings.
In case the CLIP routing function is disabled or the calling number is not included
in the CLIP routing table, the Dynamic CLIP routing table is checked. If the
calling number is found, the incoming call is routed directly to the corresponding
extension. To set the Dynamic CLIP routing function use the GSM incoming

If the incoming call is still not processed, the gateway will receive the call and
