[cisco-voip] H323 Tone on Hold

Mon Aug 11 13:56:27 EDT 2008

If you are getting tone on hold it means CUCM isn't able to allocate  
an MOH server to play the assigned MOH source configured for the  
holding device.  The frequency of the beeps can be specified at the  
gateway level (if MGCP or SCCP gateway).

To disable tone on hold for SCCP devices you set the service  
parameter for tone on hold timer to 20000.  This should affect any  
device controlled by CM (ie not H.323 gateways).

By changing the parameter you noted below to "Use ANN for Ring Back"  
this will cause CCM to invoke Annunciator to play tone on hold to the  
gateway instead of having the gateway generate it.  By having ANN  
play tone on hold, how often you hear the tones can be set via the  
service parameter.

I found this under Service Parameters>Call Manager Service. The  
choices are:

User Info for Call Progress Tone  (Default) - I have this selected
H.225 Info for Call Progress
Use ANN for Ringback

any idea what would not break my current operation but get rid of my  
Tone on Hold?

Send H225 User Info Message: <mime-attachment.gif>	This parameter  
specifies which message Cisco CallManager sends for the ringback tone  
or tone on hold. Valid values follow:
Use ANN for Ring Back: Use Cisco SCCP Annunciator to play ringback  
tone (available in Cisco CallManager release 4.0 and later)
User Info for Call Progress Tone: Send H.225 user information message  
to IOS gateway to play ringback tone or tone on hold (This is the  
default.)
H225 Info for Call Progress Tone: Send H.225 information message to  
IOS gateway to play ringback tone or tone on hold
Cisco CallManager Version 3.1 does not support the H.225 Information  
message, so choose 'User Info for Call Progress Tone' if you are  
using intercluster trunks and any of the clusters is running Cisco  
CallManager Version 3.1 or earlier. However, if all of the clusters  
are running Cisco CallManager 3.2(2a) or a later release, you can  
choose 'H225 Info for Call Progress Tone.'
  	This is a required field.
  	Default:  User Info for Call Progress Tone

Go to enterprise parameters, and uncheck "H.225 Info for Call Progress"

I do not want music on hold or tone on hold, just sweet silence!

Did you put the ccm-manager music-on-hold command in the config?   
That is still required.

I have some H323 locations and have discovered that
callers are getting "tone on hold" when placed on hold at the site   
Not happening on MGCP sites and on internal calls. Anyone have any  
idea how can I get rid of this at H323 sites?

CUCM 6.1.1b IOS 12.4.12a

Thanks!
Steve
