How to remove the ringback tone for SIP calls landing on Imagicle queues/Auto Attendants
Applies to:
Imagicle UCX Suite for Cisco UC, any version
Description:
The CUCM plays a ringback tone for incoming calls to Advanced Queuing. To remove this tone, a SIP Normalization Script can be implemented. The script processes any SIP messages coming from Advanced Queuing and discards any “180 ringing” signaling.
How-to:
Log in into CUCM
Create SIP Normalization script
Go to Device -> device settings -> SIP normalization script
Click AddNew
Click Import File and upload the attached file
Enter a name, such as “DiscardIncoming180Ringing”
Click Save
Go to Device -> Trunk
Find and edit SIP Trunk for Advanced Queuing
Within “SIP Information” section, find “Normalization Script”
Choose the script “DiscardIncoming180Ringing”
Save and Reset trunk
