Simultaneous Use of PRI ISDN and VoIP Cards
The GSM gateway enables the VoIP and PRI ISDN interfaces to be used at the same
time. This configuration requires additional incoming/outgoing call routing settings.

Licence Limitations
Some of the 2N products have time-limited software licences (e.g. DSS1 signalling,
etc.). Moreover, every gateway restart adds one hour to the internal licence counter.
To see the current licence status, use the CPU web interface (the standard licence
validity is 850 hours).
You are recommended to contact your dealer before licence expiration to request for a
new licence key to increase the gateway using time.
To upload a new licence code, use the CPU web interface.
GSM/UMTS Network Restriction
Upon the dealer's request, 2N can activate restrictions of use for selected wireless
networks only. Thus, the gateway will be unable to log in successfully to the restricted
wireless networks. This state is signalled by the red status LEDs on the GSM/UMTS
cards and the 'netw-err' message on the web interface diagnostics screen.
Tip
For an external synchronisation line you can use a standard cable with an
RJ-45 connector. To disconnect the Rx wires just release the defined
jumpers on the PRI 2 interface on the PRI board.
Caution
A gateway with an expired licence fails to accept calls from the
VoIP/GSM/UMTS/PRI interface because the call control layer is
deactivated.
