24-channel GSM gateway ELGATO K32

24-channel GSM gateway ELGATO K32 is a 24-channel GSM gateway (GSM bridge) with the possibility of expansion to 32 channels. Provides connection from mobile phone to PSTN and from PSTN to mobile phone, callback (Call-Back), connection statistics, protection from unauthorized access to the communication system.

24-channel GSM gateway ELGATO K32 - is a multi-channel (from 24 to 32 channels) GSM gateway (GSM bridge) designed to connect to a mini-PBX or IP telephony system (VoIP gateway). Each channel in the GSM gateway is essentially a mobile phone (a specialized digital GSM module is used) with its own number and can belong to any of the mobile operators. The device checks all outgoing calls, and if the subscribers who used the GSM gateway are on the established list, it routes the connection either to the gateway of another telephony operator or to the incoming channels of the city network PBX. The device is included in the oncoming PBX with a 2Mb digital PRI stream (incoming and outgoing channels, a total of 30).

Thus, any mobile phone user can call a GSM gateway connected to a mini-PBX, then dial a landline phone number and make a call to the general telephone network at a corporate rate.

24-channel GSM gateway ELGATO K32 provides:
- outgoing connection from a mobile phone to a public telephone network;
- incoming connection from the PSTN to a mobile phone;
- connecting subscribers of different mobile operators with each other without access to the public switched telephone network (PSTN);
- maintaining connection statistics;
- protection against unauthorized access to the communication system;
- wiretapping of telephones (calls passing through a GSM bridge);
- the device is made on a modern element base, has built-in means of monitoring the state of the communication system and is highly reliable;
- structurally, the device is an IBM-compatible industrial computer with expansion boards installed in it (switch and radio channel boards).
- only one high gain antenna (YAGI) can be used;
- Call-Back: in this mode, the GSM gateway, having received a call from a registered subscriber, "rejects" it and calls back to this number. This mode will allow the subscriber to save money and optimize communication costs.

The proposed device will significantly improve the quality of long-distance calls for employees of your central office and reduce the costs of long-distance communication services for out-of-town branches. Users of mobile phones of your enterprise with a low limit will have the opportunity to make calls to the general telephone network - free of charge.
