Chapter 10 Voice

Dual-Tone MultiFrequency (DTMF) signaling uses pairs of frequencies (one lower frequency 
and one higher frequency) to set up calls. It is also known as Touch Tone®. Each of the keys 
on a DTMF telephone corresponds to a different pair of frequencies.

Pulse dialing sends a series of clicks to the local phone office in order to dial numbers.

Enable Message Waiting Indication (MWI) enables your phone to give you a message–
waiting (beeping) dial tone when you have a voice message(s). Your VoIP service provider 
must have a messaging system that sends message waiting status SIP packets as defined in 
RFC 3842.

IVR (Interactive Voice Response) is a feature that allows you to use your telephone to interact 
with the ZyXEL Device. The ZyXEL Device allows you to record custom tones for the Caller 
Ringing Tone and On Hold Tone functions. The same recordings apply to both the caller 
ringing and on hold tones. 

Use the following steps if you would like to create new tones or change your tones: 

1 Pick up the phone and press “****” on your phone’s keypad and wait for the message 

that says you are in the configuration menu. 

2 Press a number from 1101~1108 on your phone followed by the “#” key.

3 Play your desired music or voice recording into the receiver’s mouthpiece. Press the “#” 

key.

The ZyXEL Device does not support pulse dialing at the time of writing.
