[cisco-voip] MOH Beeping

[Norton, Mike]

Listening to the capture, it sounds like ambient electrical/RF noise is getting into the analog audio signal. I'm surprised this isn't a more common problem. Server racks are probably one of the least ideal places to try to run unbalanced analog audio signals.

Sev3 SR 613458017 Udhay has been pretty helpful so far checking the configuration.
the sniff files are associated with that case,m you should be able to see them (otherwise I can add them in)

User experience:

I call my boss, he answers by pressing speaker button.
I place him on hold
He hears the "good.au" sound I enclosed for Peter to listen to

the sound is not unlike rapid repeated whistling...
I should note that when I use the handset I don't hear it, but when I capture the packets it is still there, just not as loud

In the very abstract this sounds like call waiting tone.  Can you clarify exactly what the user is doing when "caller is placed on hold and the speaker is activated"?  What buttons is the user pressing to accomplish this?

concurrent detailed CCM and SDL traces and a packet capture of all traffic to/from the phone could be used to isolate the source of this tone rather quickly.  You mention a TAC case, what is the number?

Okay I have a TAC case open and I have tried changing configuration settings, cables and hardware...

CUCM 7.0.2.2000-5
Fixed audio from XM radio (MOH-USB-AUDIO) card

when a caller is placed on hold and the speaker is activated there is an audible (and quite annoying) beeping sound playing over the top of the audio file.

It is not audible on the handset or headset.

If I sniff the phone port and capture the audio file I can hear it.

If I record the audio file with my laptop (plugging mic cord into lappy instead of MOH-USB) there is no beeping.
In my mind that eliminates the XM radio and cables, I have changed out cables though, just in case.

I changes out MOH-USB cards and that also did nothing to eliminate the issue.

I have upgraded firmware on the phones and that wasn't it either.
With the Sample Audio file (which is JAZZY) there is no beeping regardless of handset or speaker.

Any suggestions?
