GT10M-P acts as a bridge between the PBX and GSM network to ensure that calls made from phones connected to the PBX in the company to the mobile phones are charged with cheaper GSM call rates.

• It is possible to achieve great discounts in GSM calls made by the employees from the phones connected to the PBX.
• Employees who are out of the office can benefit from the same discount rates for the phone calls they make from their mobile phones to their company.
• Making GSM to GSM calls instead of long distance calls over fixed lines in companies having multiple branches or those high amount of long distance calls, it is also possible to benefit from discounts over 80%.
• GT10M has a single GSM module by default.
• Its capacity can be doubled with an additional module.
• Polarity Reversal feature allows reversing of the poles of the line, and thus detection of this change by an equipment (PBX) connected to this line. This prevents concerns such as hanging up of the line.
• Thanks to the Smart Call Back Feature, if an extension makes a GSM call through GT10M-P and the called party does not pick up the phone, when the called party dials the number which is listed in his mobile phone as a missed call, the call is forwarded automatically to the extension (instead of the company operator) who initiated the first call.
• calls the number of his/her company displayed in his phone as a missed call back. The call is not directed to the operator.
