Businesses which aim for lower costs, extra spread or improved flexibility in their networks may opt to integrate their phone systems to a gateway working through the GSM (Global System for Mobile Communications). GSM gateways are typically used to translate voice between Cellular networks with VoIP phone systems or PBX; enable low-cost Call-to-SIM and SIM-Channels connection of a land-line.
There are varieties of GSM gateways in the market. Among the features to be considered must include reading your SIM card slots, whether it is suitable for both VoIP and traditional PBX system, and if it is compatible with your network.
If you have a VoIP System (based on SIP): check if the GSM gateway supports your IP PBX or VoIP server. Some gateways provide SIP support and may be directly connected to IP-based components. For Analog Systems (PBX): If you have a classic PBX system, just plug in the GSM Gateway to the PBX via FXO ports (FXO is for analog connections).
Once the GSM gateway connection has been established, just insert your SIM in one of slots! (make sure SIM cards are active, ready to make calls etc.) Depending on your needs (i.e., international calls), some systems will let you choose which SIM should be used for outgoing calls.
Access the web base of your GSM gateway (using a browser, type its IP address). From here, you can:
After everything has been plugged in, test call a few times to ensure that the gsm gateway is functioning. Both dial in and out should work fine. Monitor and Adjust Settings To view statistics, signal strength and usage, go to the management web interface of the GSM gateway. Fine-tune the settings, if you have problems with your computer's performance or security.
Low Signal Strength : Position your GSM gateway in an area with optimal cell
phone
signal. It might be a good idea to invest in an external antenna for improved
coverage.
SIM Card Limitations : Some carriers do not allow the use of SIM cards with GSM
gateways.
Make sure the SIM cards work with your configuration and are voice enabled.
Poor sound quality : If you have low-quality audio or the call is dropped it's
possible
that there are network issues, or your settings may be incorrect. Double-check network
settings and firmware updates.
Integrating your phone system with a GSM gateway allows your business to take advantage of lower call costs, flexibility and improved communication features. Regardless whether you are currently using an older PBX, hybrid or IP-based system VoIP-GSM gateway can route fixed-to-mobile and mobileto-fixed calls at no cost (or by choosing a cheaper mobile operator, -it depends on your country) via built-in SIM card module.
