VoIP - GSM gate complex Polygator - includes capabilities of GSM and VoiP gates VoIP - GSM gate complex Polygator establishes telephone traffic exchange between GSM and IP NETwork. The application of the given equipment in a corporate network allows to make calls from mobile GSM subscribers to IP network and on the contrary, the mobile subscribers can have a call from subscribers of a corporate network. The system also can be applied in operator business, for transferring the traffic from GSM network to IP network, for example, for organizing iinternational calls trough networks of the IP-operator. |
VoIP - GSM gate complex Polygator establishes telephone traffic exchange between GSM and IP NETwork.
The application of the given equipment in a corporate network allows to make calls from mobile GSM subscribers to IP network and on the contrary, the mobile subscribers can receive a call from subscribers of a corporate network. The system also can be applied in operator business, for transferring of the traffic from GSM network to IP a network, for example, for organizing international calls throughout networks of the IP-operators.
The transmission of the traffic in VoIP-GSM gate is organized through the protocol SIP, H.323.
A quality of voice transmission depends from audio-codec: G.711, G.726, G.729, G.723.

The basic characteristics
Function of a return call - CallBack
With an incoming call the GSM gate determines and compares telephone number of the calling subscriber with numbers of the subscribers, for which the function CallBack is permitted(subscribers database). If such number is found, GSM-gate breaks off connection and calls back him itself. If there is no such number in database the GSM gate either forbids connection or switches the subscriber according to the given route.
Calls restriction
With the help of prefix device determines the route of call and then compares it with number in database and either allows call or forbids them.
Possibility of recording of a voice greeting DISA
There is an opportunity of recording of a voice greeting in GSM gate Polygator, voice greeting will be reproduced to the calling subscriber just after connection.
Least Cost Routing Function
The outcoming call is routed according to the prefix mask taken from database.
Automatic telephone number recognition
The function allows to determine number of the calling subscriber and either forbid or permit transfer of SIM number that established in a GSM gate .
Time conversation restriction (Max. of called minutes)
A limit of conversation can be set up for each SIM card
Programming
The GSM gates is programmed through the console or with the help of software working under Windows( CallCentre module). The programming can be implemented both locally and remotely.
Software updating
For updating the version of the software it is possible to use either applied CD or manufacturer(our) WEB-site. Updated software is given for free-of-charge.
Statistics of calls (CDR)
The device stores the detailed information about all outgoing and incoming calls (up to 500000 records)
LOG-file
The information about device condition is written in LOG-file: set up, initialization, arising of mistakes etc.
External antenna combiner
Due to external antenna combiner the signal from 8 GSM channels passes through only one external ( directed) antenna.
Technical characteristics
