Call Scenarios

ATA Administration Guide

105

The ATA has configurable call progress tones. Call progress tones are generated 
locally on the ATA, so an end user is advised of status (such as ringback). 
Parameters for each type of tone (for instance a dial tone played back to an end 
user) may include:

•

number of frequency components

•

frequency and amplitude of each component

•

cadence information. 

When one VoIP account is shared between the FXS and PSTN Lines, the following 
parameters are recommended to be set. See the Regional page in the 

 for these and other call progress tone parameters.

This section describes some typical scenarios where the ATA device can be 
applied. Some terms are introduced in the first few sections and reused in later 
sections. This section includes the following topics:

•

•

VoIP PIN Tone

This tone is played to prompt a VoIP caller to enter a PIN number.

PSTN PIN Tone

This tone is played to prompt a PSTN caller to enter a PIN 
number.

Outside Dial Tone

During two-stage PSTN-gateway dialing and with a dial plan 
assigned, the ATA device collects digits from the VoIP caller and 
processes the number using the dial plan. The ATA device plays 
the 

Outside Dial Tone to prompt the VoIP caller to enter the 

PSTN number. This tone should be specified to sound different 
from the PSTN dial tone.
