Whether you have used System Configuration or Pack Configuration to configure the telephony environment, you might need to set suitable values for system parameters in the Trunk Interface parameter group.
Note: In some countries, the telecommunications authorities have
ruled that parameters that affect the connection with the telephone network
must be performed by an Blueworx representative. For this purpose, a special
password-protected administrator profile, field, is provided, which
gives access to field-level parameters, including the Line Code and Framing
Mode parameters.
