I am not familiar with the recording system you use, but there is something in Call Manager that may be appropriate. This is often configured when you set up CUCM silent-monitoring for CTIOS.
Monitoring Notification Tone
A monitoring notification tone can be configured using the Service Parameter Configuration page in the CCM Administration Interface. There are two entries:
- Play Monitoring Notification Tone to Observed Target
When set to true, this option will play the tone to the monitored party (usually an agent).
- Play Monitoring Notification Tone to Observed Connected Target
When set to true, this option will play the tone to the party to which the monitored party is talking (usually a customer).
A monitoring notification tone can be configured using the Service Parameter Configuration page in the CCM Administration Interface/ Select Server/ Select Cisco CallManger (active) for Service. Look for "Clusterwide Parameters (Feature - Monitoring"). If these are set to true, set them to false and see what happens. A CM restart may be required.
