If your gateway is H.323 then the CM timers have no effect. CM just
tells the gateway to play tone xx and that corresponds to tone on hold.

I did 'debug voip dspapi detail' and 'term mon', but no output. I'm
sure I'm using this voice-port because there's only one on the router
and when I do a 'show call active voice compact', I see the call there.
I do not have 'MTP Enabled' in CCMAdmin.
I just sent another email, but the Tone on Hold seems to only take
effect on IP to IP calls, not IP to gateways calls. Is this normal
operation?

in h323 we only send a message to the GW that says 'hey, play tone 53' ,
well maybe not 53, but still just an index into an array.
if changing the OA on the voice port did not make a difference, then are
you 100% certain the call is routing through this voice port? was the
ipphone user's voice notably softer when you performed the test?
on the gateway when call volume is low turn on 'debug dspapi detail'
or 'debug voip dspapi detail' depending on your IOS version:

ios124/124tcr/tdb_r/dbg_d1ht.htm#wp1083071
and look for a message like:
Aug 27 22:02:49.159: //19930/9C188849A6CA/DSPAPI/[1/0:23 (19930)]/
dsp_inband_tone_on:
Tone ID=1, Direction=1, Num frequencies=2
Frequency(hz): a=440 b=480, Amplitude(dB): a=-16.0 b=-16.0
Cadence1(ms): ON=2000 OFF=4000
Cadence2(ms): ON=0 OFF=0
Cadence3(ms): ON=0 OFF=10000
Cadence4(ms): ON=0 OFF=0
Frequency(hz): a2=0 b2=0 a3=0 b3=0 a4=25799 b4=39688
ITO option group: 1
Aug 27 22:02:53.027: //19930/9C188849A6CA/DSPAPI/[1/0:23 (19930)]/
dsp_query_info
Anyone know offhand what telephony tone is 440+480?
Do you have 'MTP Enabled' select on your h323 gateway config in
CCMAdmin?

I tried setting the output attenuation to 6 and that did not seem to
help. I also changed the Tone on Hold Timer to 200000 and 0, but it
kept playing every 10 seconds. The Tone on Hold Timer documentation
says for non-MGCP devices, if it's set to 200000, it will not play, but
it still plays. This seems to be the best solution for me if it works.
I'm on H.323 gateways. I've restarted my phone, but not the
CallManager. Doesn't these clusterwide settings take effect
immediately? Do I have a possible bug?
By the way, the beeps are LOUD. Loud to the point where you have to
take the phone off your ear.

You can also adjust the "Tone on Hold Timer (sec)* "
timer under call manager service parameters. If you set this to 200000
the tone will be disabled.
