How to Modify Application Delays
Only application delay indexes for PBX tones that fail should be modified. Before modifying
an application delay index, use the PRT (PRint Tone) command and COS Attribute 70 —
MEASURE PBX TONES to determine the correct timing value.
1. Assign COS Attribute 70 to a test mailbox that has an extension number of a telephone set
located near the terminal.
When a mailbox with COS Attribute 70 is called, the VP 300 dials the extension number,
stays on line for ten tone changes, and then hangs up. During this call, the tone cadence of
the PBX can be determined.
☞
The extension called should not be set to forward on ring-no-answer, busy, or fast
busy. Other features, such as camp-on, must be disabled. This could give false tone
cadence.
2. Select a VP 300 port and at the @ prompt enter
PRT x
where x is the port number to be used.
3. Call that port’s extension number.
4. When the system answers, dial the test mailbox number.
The PRT command monitors and displays the DTMF tones dialed by the caller, the DTMF
tones dialed out by the VP 300, and the call progress tones from the PBX to the terminal.
This command is a real-time command, and can be initiated on only one port at a time. The
information is not stored.
☞
If the tones do not show when the PRT command displays the DTMF events, at the
@ prompt enter
C S
Repeat from step 2.
The PRT command should be initiated for any call condition that fails, such as when the
system calls an extension that is sending ringback but the system detects an answer
condition.
