Controllable switching between BTS by the GSM-gateway

gsm-gateway-base station_switch

GSM-gateways Polygator allow to setup special mode of interaction between the GSM-gateways and Base Transceiver Station (BTS). For example, there is special mode for switching automatically between visible 6 base stations on certain conditions.

Switching among BTS is performed during pauses between voice calls. Frequency of BTS switching is set by randomized time bounds. Besides, some of visible base stations can be excluded from the list. The list is available on the web-interface of GSM-gateway and accompanied with some additional information. Operation mode and base stations list can be set up for each GSM-module individually.

VoIP-FXS gateway for 40 channels in 19” chassis


VoIP-FXS gateway Polygator is available in chassis for 19” rack installation. Chassis height is 1U, material - metal. Having 40 FSX-ports gateway enable you to integrate modern telephony technology like international SIP-trunks quickly even with old analogue desktop phones.

VoIP-FXS gateway Polygator can be equipped with up to 40 FXS-channels providing direct connection of regular analogue phones. Some FXS-channels can be replaced with FXO-channels (for receiving analogue lines), as well as with GSM-ports and UMTS/GSM-ports for direct SIM-card insertion or for remote SIM-cards commutation.

The gateway can be used for fast integration of SIP-telephony in offices, hotels and any other institutions with big number of analogue line phones. Besides, the gateway have IP-PBX Asterisk installed, which can be engaged optionally. Enabling on-board IP-PBX software will turn gateway into standalone full-functional mini-PBX.

SMS-gateways Polygator – universal solutions for SMS, USSD, STK and QoS


Polygator GSM-equipment is capable of performing tasks not only for voice telephony but also for establishing full-scale SMS-solutions. By using GSM-gateways or GSM-cards it is possible to perform bulk SMS-sending and receiving of SMS in GSM and UMTS networks, execute USSD-requests and perform testing of mobile network services quality.

It is possible to integrate device in any system by protocols HTTP, SMPP, Email-SMS, AT-commands via TCP/IP directly to the GSM-modems and others. By using GSM-cards Polygator under IP-PBX Asterisk it is possible to work with SMS via SQLLite database or dialplan. In order to use the Gateway as QoS probe it is possible to setup custom script execution on each event. The script can be written on any scripting language supported by Linux Shell and will be executed each time event detected by software. For example, the system can perform HTTP-request to remote server each time SMS or Call received. Such HTTP-request may include additional information like caller number, IMSI of receiving SIM-card, data about BS and additional timing information.

For creating big-scale systems it is worth to consider the use of SMS-gateways with SIM-banks and SIM-server software. By using a SIM-bank you can save time on processing hundreds of SIM-cards, automatically perform SIM-card activation and using cheap SMS-plans. The system will automatically rotate SIM-cards in GSM-gateways in order to keep constant service availability. Additionally, Polygator SIM-server software can be controlled by external systems via an API.

Support for analogue lines FXO and FXS in GSM-gateways/IP-PBX Polygator G20

G20 with FXO and FXS

G20 series GSM-gateways are capable to commutate calls not only to GSM but also to landlines (PSTN) as well as to connect analogue phones. Adding analogue FXO-ports and FXS-ports are as simple as adding GSM ports - by installing extension boards.


Currently, them maximum allowed number of FXO-ports are 4. Number of FXS ports is limited to 40.The maximal number of GSM-channels are 24.


For example, by installing G20 equipped with 24 FXS-ports, 4 FXO-ports and 4 GSM-ports, you will have multifunctional Asterisk-based IP-PBX. It will provide you with all modern IP-PBX features (voice menu IVR, call recording,...) and will commutate 24 analogue desk phones, 4 landlines and 4 SIM-cards.


Money saving opportunities:
1) you don't buy standalone PC-server for IP-PBX

2) you are not forced to change analogue desk phones to SIP-phones

3) all users save money by calling via GSM-gateway
