This article describes the setup of the GSM gateway MV-370 (Mobile VoIP) from PORTech Communications Inc

Configuration example

The GSM Gateway must be registered to the GSM network as a regular mobile phone subscriber, and needs to be equipped with a SIM card. Via the gateway calls can be made from the AlphaCom E to the GSM network, as well as from the GSM network in to the AlphaCom E.

Because the MV-370 needs to registrer to a SIP server, the AlphaCom must be equipped with license for SIP phone (not SIP Trunk license!).

Configuration of the MV-370

The MV-370 unit is configured via a web interface. The default IP address is 192.168.0.100, mask 255.255.255.0. The default IP address can be set by pressing the reset button (located next to the SIM card) for 3 seconds. Other settings will be kept. Before accessing the web page, confirm that the IP address of the configuration PC is on the same subnet, e.g. 192.168.x.x.

  • Username: voip
  • Password: 1234

Network settings

Network Settings

Change the network settings according to the network environment. Select Network > WAN Settings:

  • IP Type = Enable Fixed IP
  • IP = IP address of the Mobile VoIP unit
  • Mask = Network mask
  • Gateway = IP address of the network gateway

SIP settings

SIP Settings

In the menu SIP Settings > Service Domain, enter information for "Realm 1":

  • Active = ON
  • User Name = Any text, used for Caller ID. This text will be shown in the display on incoming calls from the GSM network, together with the telephone number
  • Domain Server = IP address of the AlphaCom
  • Proxy Server = IP address of the AlphaCom

Status will show Registered when the gateway is registered at the SIP Registrar server in the AlphaCom.

  • SIP Settings > DTMF Setting: Enable Send DTMF SIP Info

Routing Mobile to LAN

Select Route > Mobile to LAN Settings
Alternative 1 (default):

  • CID = *
  • URL = *

With this setting there will be a second Dial-Tone presented on incoming calls from the GSM network. The user must dial the intercom number. The dialling can be terminated by '#', or alternatively one can wait for 5 seconds and the call will be established.

Alternative 2:

  • CID = *
  • URL = 101

With this setting incoming calls will automatically be connected to station 101 in the AlphaCom.
