my:connection is a GSM-based solution which replaces landline-based telephony.

A standard telephone is connected to my:connection, but the product communicates via the GSM net instead of landlines.
You can also connect a standard telephone to the equipment and call via the landline net, but communication goes via the GSM net instead.
my:connection is used where landline telephony call charges are too expensive, where landlines are too expensive to install or where it is not possible to access landlines.

my:connection can be used at an advantage in warehouses, telephone boxes, recreation homes, business offices, portacabins, door entry phones and alarm systems.

Or why not use My:connection with the office switchboard as an outside line. Because it works via GSM, call costs will be much lower.
