Voice/Fax Operating Procedures

The Voice/Fax Operating Procedures begin with displaying the Voice/Fax Channel parameters and then executing the commands to change the default parameters to fit your specific voice or fax needs. The Voice/Fax Channel parameters are displayed for both channels and contain general parameters for each channel such as destination channel number through silence suppression. The local and remote interface types define the specific type of interface and the conditions that govern that interface. Not all the parameters for a particular interface apply, such as 2 or 4-wire, and dialtone or wink do not apply for an FXO interface. To change a default Voice/Fax Channel parameter, refer to the Voice/Fax Channel Commands in Chapter 5.
