No DTMF tones (WINK protocol)
If voice response applications are not responding correctly to caller input, you may suspect
that DTMF tones (the tones that identify the called number) are missing. For calls handled
with the WINK start protocol, run a trace to determine if the NMS card is receiving the tones.
To set up the trace:
1. Set the following values in the cta.cfg file:
― Tracemode=1
― Tracemask=allevt
― Tracefile=cta.log
2. Stop and start the voice system.
3. Review the ctdaemon file.
The system displays trace output.
4. Check the trace output to determine whether digits are being sent.
In the trace output, the digits in parentheses for the val field identify digits sent. In the
sample trace output that follows, val entries indicate that the digits 1, 2, and 3 were sent.
(The digit 3 is not significant, and the val entries are in bold here to help you find them.)
