What's a VoIP GSM Gateway?

A VoIP GSM Gateway enables direct routing between IP, digital, analog and GSM networks. With these devices (fixed cellular terminals) companies can significantly reduce the money they spend on telephony, especially the money they spend on calls from IP to GSM. The core idea behind cost saving with VoIP GSM Gateways is Least Cost Routing (LCR).

Through least cost routing the gateways select the most cost-effective telephone connection. They check the number which is dialed as well as rate information which is stored in an internal routing table. Because several SIM cards and GSM modules are integrated within the VOIP GSM Gateway it is able to make relatively cheaper GSM to GSM calls instead of expensive IP to GSM calls.

Who offers VoIP GSM Gateways?

Currently (2006) there are only few companies offering VoIP GSM Gateways:

See especially (alphabetic order):

- QuesCom from France (QuesCom 400 IP/GSM was one of the earliest products on the market)
- NovaTec from Germany (NovaTec are the pioneers of GSM Gateways) and offer an all in one solution IP/GSM/ISDN no extra equipment needed.
- VIERLING from Germany (offers high quality and highly sophisticated SIM management enabling maximum cost reduction)
- 2N from Czechia (VoiceBlue also was one of the earliest VOIP GSM Gateways on the market; offers SIP AND H.323)

NovaTec

NovaTec now offers the first on the world market TransNova® Internet Pathfinder (TIP) the combiner and advanced application between VoIP, ISDN and GSM. Which integrates your current telephone equipment either in Transparent mode or in SIP Protocol.

With no need to change your ISDN Infrastructure (fax, data and video conferencing), in fact the gaining of more advanced features such as least cost routing for telephony, fixed network, GSM Calls and also internet telephony, and allowing high double figure savings in your telephone bills, this is the killer application to rival the already killer application VoIP.

The ISDN structure is transported fully transparently into IP Data, therefore allowing for example your employees to completely mirror their workplace anywhere in the world where an IP network is available, also allowing you to mirror all your ISDN Features in the workplace direct to your home office, starting from Video door cameras and even video conferencing, and going as far as allowing all calls made to your office, being able to be taken in your home office at the company's expense over the Internet, and for companies with sub-branches abroad can now speak to their employees in these office free of charge, or when used in conjunction with the TMG if into the Mobile network, for the cost of a local Mobile to Mobile call.

NovaTec are the pioneers of GSM Gateways, SIP Gateways,VoIP Gateways and Encryption Gateways , in the digital compact form.

TransNova Mobile Gateways in the PRI range with inbuilt VoIP, these range from the TMG S6 with 4 - 16 GSM channels and can be fitted with up to 4 x E1's and have 4 Simcards per GSM channel, also the possibility to send Email - SMS - Email and a wide range of other features that is listed in the TMG Features list, this can be downloaded from the website at: www.novatec.de these are call through gateways and need no adjustment on already installed PABX's, as this can be used also for least cost routing etc.
The next range is the TMG S20 with from 4 - 60 GSM Channels (Completely Modular and hot pluggable) these can also be fitted with up to 4 x E1's so different interfaces can be connected, e.g. Voip and PABX, with the Least cost routing being done within the TMG. These are also call through so can be fitted before the PABX or after.
Other features include Call back options, from GSM or Fixed network, and also all systems come complete with antenna combining units with no extra costs being charged for this or other features, all are available with real time remote monitoring over IP, ISDN dial up or Local connection. Also realtime ASR monitoring is available with a spill over programm which lets you know if you have enough GSM Channels for the amount of traffic being terminated, if the ASR falls (down to simcard level)below a certain percentage then the system will send a report either by email or SMS to the network controller so ASR rates can be monitored and adjusted.
Antenna rotating systems can also be offered where the Antennas can be moved between base stations, randomly or as timed events, so taking pressure of the network providers when not enough capacity exists on individual base stations (also to hide the effect that the traffic is being terminated through a GSM Gateway).
All GSM Gateways will also be able to be used with the Sea of Sims (Simserver) this is a new application available for the TransNova where any number of GSM gateways can be installed in various locations without Simcards, these are held in a central location (Local SCU) and have a direct IP connection to the terminating units (remote location), the remote gateways request the simcard information required via the IP link and the SCU passes virtual sim information to the Gateway which using this information can terminate the GSM Calls. In the remote location GSM Gateways are local backup Sims for the eventuality that there is an IP breakdown. The SOS then takes away the restriction of how many Simcards can be used per GSM Channel. All Simcards are configurable per time, Budget or amount of minutes, and individual CDR's can be produced per Simcard.

SunComm SC-375 Voip GSM Gateway

This is a product distributed, in Italy, by Altesys, which offer the ability to gateway GSM traffic via SIP protocol and vice versa.
It has an external antenna with about 2.5m of RG174 coax cable, and works with asterisk configuring:
sip.conf
[09]
type=friend
host=dynamic
username=09
secret=12311
mailbox=10
dtmfmode=inband
call-limit=1
insecure=very
context=default

SC-375 configuration
There are several parameter to configure, very normal for people who have already configured other SIP device.
A special note that should be taken into account is the routing parameters to permit LAN to MOBILE and MOBILE to LAN:

• in 'Mobile to LAN settings' set a rule with CID = '*' and URL = '0' or the extensions to enter in the dialplan to reach the IVR menu for the incoming calls from GSM network;
• in 'LAN to Mobile settings' set URL = '192.168.0.1' or the IP number of the asterisk PBX, and Call Num = '#' to enable outgoing callings from asterisk to any number through GSM network.

MV-370 GSM to SIP Gateway

That VOIP GSM gateway can be directly connected to any SIP IPBX.
It is manufactured by Portech, a Taiwanese company.
Main advantage of that gateway is the direct SIP connexion, which makes the voice quality very good.
Another advantage is the price : you can buy it for about $150 on ebay.

Firmware and manual are available at http://www.portech.com.tw/eweb/index1.htm.
As the product is still very young there is little info on the net about it.
To avoid instability problems, be sure to flash the latest firmware before any configuration.
If you want to connect that box to Asterisk, I've written a how-to available at http://www.voip-info.org/wiki/view/Setup+MV-370+GSM+Gateway+with+Asterisk

I hope it will make you gain lots and lots of days of setting up and adjustments :-)
