Call Progress Tones
Progress messages are described as follows:
Learning
The Gateway has gone off hook and dialed the destination address. It is collecting raw data on
the call progress tone.
Analyzing
The Gateway is analyzing the raw data to extract the tone characteristics.
Comparing
The Gateway is comparing the new tones to existing tones and other new tones for possible
conflicts.
Validating
The Gateway is redialing the destination addresses and testing to see if the new call progress
tone definitions can detect the tones.
The Cancel button cancels the current session and returns to the Learn Tone Web page.
4.2.4 Learn Tone Results
When the Media Gateway has finished learning the tones, a results page is displayed.
The learned tones are grouped into the following possible tone results on the Web page:
• Tone Errors
• Existing Tones
• Unique Tones
• Conflicting Tones
After selecting the tones to be added to the tone definition table, the Apply button adds the selected
tones to the tone definition table. The Manual Tones Web page discussed in
Section 4.1, “Viewing
and Editing Call Progress Tones” , on page 191 can then be used to view the newly learned tones.

to the configuration due to the error encountered. Possible reasons for error as well as possible
action include the following:
No data

be collected.
Action: Verify the destination address.
Not enough data
The Gateway dialed the destination address but the data collected was not enough to extract
tone characteristics.

another extension or that the destination is not answered.
