[cisco-voip] DTMF Tone problem?

[Daniel Rodriguez]

Might also want to stay away from DSPWare 4.4.21 and 4.4.29.
Duplicate DTMF events are produced when encountering defect ID CSCso87127, which I've seen mainly when using the DSPWares mentioned above.
Just a heads up... But this may not apply to you depending on the call flow and equipment you're running.

Other way around.

the bug when using the hand set would send dual touch tones.  by using the speaker phone is worked around the issue.

but John is correct.  I think it was right around the 8.3 and 8.4 firmware and if I remember correctly it was 79x1 and better.  (like all the java phones)

Just my two cents.

We had similar problem, was due to firmware on phones.  We had 7945/65/75 running (I think) version 8.4.3 or 1 earlier.

Upgrade phones to newer firmware, problem fixed.



When users used the speaker phone to press keys for automated system, it would not work or generated wrong DTMF tones.

If they used the handset, it worked fine.



May not be the same problem your experiencing but HTH.

I have had a few problem calls today regarding callers not being able to choose options from menus when they are calling out.  The tones are not being recognized.  The problems are intermittent.  Anyone familiar with this problem?

Thank you,

Lisa
