3.2 Call Routing Principles
2N BRI Lite
®
The gateway is equipped with one BRI ISDN and one VoIP-SIP ports. You can select
one of the following incoming call processing modes for each of the ports via the web
interface:
Use LCR table – in this case, calls with be routed as set in the LCR table
Reject calls – all incoming calls will be rejected
Route to port – all calls will be routed to the selected port without change
If your BRI gateway is connected to a PBX subscriber line, you can activate DTMF. If
you do so, the GSM gateway automatically answers any incoming call from BRI ISDN
and offers the caller dialtone for another DTMF dialling. The call will then be routed to
the GSM/UMTS modules.
Incoming GSM/UMTS calls can be either DTMF-processed or automatically routed to the
ISDN BRI / VoIP-SIP interface according to the active intelligent GSM gateway rules
functions (Auto CLIP, CLIP routing). They are routed to the ISDN NT or ISDN TE
interface depending on the GSM gateway configuration.
Incoming GSM/UMTS calls can also be rejected and, with the aid of CLIP, used for
CallBack.
The LCR algorithm routes outgoing calls on the basis of the call type, current time
tariff, day in a week and, if available, free minutes of GSM providers.
