Working with Call Progress Tones
Not enough data
The Gateway dialed the destination address but the data collected was not enough to extract
tone characteristics.
Action: Verify the destination address and ensure that the destination does not forward to
another extension or that the destination is not answered.
Failed Validation unexpected CP tone
The Gateway dialed the destination address and was able to extract tone characteristics, but
when the Gateway dialed the destination address to validate the newly learned tone, an
unexpected call progress (CP) tone was detected. The detected CP tone is listed in the error
message. This detected CP tone did not match the newly learned tone or any expected
conflicts. This detected CP tone may be a tone that already exists in the tone definition table or
another newly learned tone.
Action: Using the listed tone characteristics and the unexpected tone event that was detected,
it may be possible to compare tones and determine which of the tones was actually detected. If
the tone definitions only overlap in the time deviation, then it may be possible to manually add
the tone and adjust the time deviation of the new tone and the conflicting tone to give two
unique tones. If the two tones are the same, then only one tone can be used.
Failed Validation Timeout
The Gateway dialed the destination address and was able to extract tone characteristics, but
when the Gateway dialed the destination address to validate the newly learned tone, no CP
tone was detected.
Action: Validate the destination address.
Existing Tones
The tones listed in this section were successfully learned but found to match tones already in the
configuration. Since these tones are already in the tone definition table no further action is needed.
Unique Tones
The tones listed in this section were successfully learned and validated without error or conflicts. If
the "Add tone to Configuration?" check box is checked, these tones will be added to the tone
definition table when you select the Apply Changes button.
Conflicting Tones
The tones listed in this section were successfully learned but were found to conflict with other
tones. You can select only one of the conflicting tones to be added to or kept in the configuration. If
the tone that conflicts with the selected tone is already in the tone definition table, it will be deleted
when you select the Apply Changes button. If the conflicting tone is another newly learned tone, it
will be ignored.
Note: If the conflicting tones do not overlap by much and it is desired to keep both conflicting tones, you
can print the results page or write down the tone characteristics for the conflicting tone and add it to
the tone definition table manually. You will need to manually adjust the tone characteristics of the
conflicting tones to remove the conflict.
