Chapter 9 SIP
• G.729 is an Analysis-by-Synthesis (AbS) hybrid waveform codec that uses a filter based
on information about how the human vocal tract produces sounds. G.729 provides good
sound quality and reduces the required bandwidth to 8kbps.

9.1.9 PSTN Call Setup Signaling

PSTNs (Public Switched Telephone Networks) use DTMF or pulse dialing to set up telephone
calls.
Dual-Tone Multi-Frequency (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.

9.1.10 MWI (Message Waiting Indication)

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

9.2 Custom Tones (IVR)

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.
