a caller puts the other callers on hold, the others hear TOH which is of course distracting. I would like to mention that we have already disabled TOH on CME and CUCM.  On CME using a blank MOH audio. 

Below is the present results.

1) CUCM user puts CUCM user on hold - No TOH

2) CME user puts CME user on hold - No TOH.

3) CME user puts CUCM user on hold - No TOH.

4) CUCM user puts CME user on hold - TOH is present.

We do not want the TOH even in the case of number 4 above
