Displaying the IMEI
The IMEI (International Mobile Equipment Identity) is a serial number that permits unique identification of the hardware in mobile radio equipment. This number allows different network providers to block the telephone in the event of misuse.
Switching 3-way calling on and off
Problems may occur with 3-way calling on the PCM, as these functions are not correctly supported by all cell phones and telephone networks (in particular CDMA networks).
This function is only available if your cell phone is connected to the PCM using the Hands-Free Profile.
This function is only available with the SIM card inserted or with a connection using the SIM Access Profile.
