J-18 INSTALLING TELEVANTAGE
Defining custom tones ____________________________________
Custom tones can be defined for incoming fax detection and disconnect detection. (Disconnect
tone is an issue for analog trunks only. Robbed-bit T1, E1 CAS, and ISDN PRI trunks do not,
in general, use an in-band tone to signal a disconnect.) For a detailed discussion of custom
disconnect tones, see the TeleVantage Knowledge Base article #1099, “A Practical Guide to
Custom Disconnect Tones.”
You can define one incoming fax tone and up to ten different disconnect tones under the
following Windows registry keys:
HKLM\SOFTWARE\Artisoft\TeleVantage\Server\ToneDefinitions
\IncomingFaxTone
HKLM\SOFTWARE\Artisoft\TeleVantage\Server\ToneDefinitions
\DisconnectTone<n>
where <n> is a digit from 1 through 9 (for example, \DisconnectTone1, \DisconnectTone2,
and so forth.)
Custom trunk disconnect detection tones are used in installations where a PBX sits between the
central office and TeleVantage, and where the PBX provides a tone to indicate trunk hangup.
By default, defines a
DisconnectTone1 as a fast busy tone.
After you enter custom tones, you must restart the TeleVantage Server. At startup, TeleVantage
will read the definitions for all custom tones and define them to the Dialogic drivers.
Note:
Use the information in this section to define custom disconnect tones via the Windows
registry for all Dialogic telephony boards that provide analog trunk resources, except for the
following boards: DI0408LSAR2, DM/V160LP, and DM/V160LPEU. For these boards, you must
edit the Dialogic .config file associated with the board. For more information, see the TeleVantage
Knowledge Base article #1099.
Each custom tone is defined by the DWORD values listed in the following table.
Custom Tone Keys
Key Description
freq1
First frequency (in Hz) for the tone
freq1dev
Allowable deviation for the first frequency (in Hz.) This allows
TeleVantage to use a range for detecting the tone, instead of an exact
frequency.
freq2
Second frequency (in Hz) for the tone
freq2dev
Allowable deviation for the second frequency (in Hz)
cadence
Enables or disables cadence. 1 = enabled and 0 = disabled.
minrep
Number of repetitions for the cadence (that is, the number of times that the
on/off signal is repeated)
dualtone
Specifies whether the tone is a dual tone or single tone. 0 = single tone and 1
= dual tone.
cadenceon
Length of time for which the cadence is “on” (in 10ms units)
