Installation and Operation Manual
VoIP Gateway
10
To prevent calls from being accidentally interrupted, your VoIP Gateway informs you if a
restart is required.
3
Click the “Reset is required” link. The Reset when idle view will open.
4
Click “OK” to restart when there are no active calls (this prevents existing calls from
being disconnected by a restart) or select Reset > Reset, and click “OK” for an
immediate restart.
Note:
When waiting for a Reset when idle, do not browse away from the screen, or the
reset will be cancelled. The “ok” shown in the browser notifies you that the reset has
begun and will be ready after approximately 5 seconds.
If the new configuration was not performed properly, the VoIP Gateway might no longer
be accessible after activating. That would be the case, for example, if an Ethernet interface
parameter such as an IP address or subnet mask is set incorrectly. In such a case the
Management port can be used, since it is no longer possible to fix the mistake by using
the GUI.

Generate the Default Configuration
You can return to the default configuration at any time by pressing the reset button and
holding it down (5 - 10 seconds) until the LED starts flashing. The parameters are reset and
the VoIP Gateway will then restart in tftp mode (after further 4 - 6 seconds). Then switch
the device off and on again to return to DHCP client mode. See
IMPORTANT:
You will lose all licenses as a result of this procedure. Download the
installed licenses from the VoIP Gateway and save them before deleting
the configuration, see
Note:
You will also lose all of the preceding configuration. If required, you can save the
current configuration in a file, beforehand.

Configuration Information
We describe the configuration procedure using the Web Browser, which is usually the
most convenient one for common application scenarios. Configuration via Telnet is
possible but not recommended and is not described in this manual.
Note:
Ascom do not support calls through firewalls but if required (i.e. if access to the
VoIP Gateway must be protected by a firewall) the services tcp/23 (telnet) and tcp/80 (http)
need to be enabled. Refer to section
Tip:
Press the reset button again, briefly, to return the VoIP Gateway to normal operating
mode. In this case however, the DHCP server mode will be activated (see
Setting the IP-interface parameters without DHCP
on page 152), whereas the DHCP
client mode will be activated after switching the VoIP Gateway on/off.
