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:

1. Log in into CUCM

2. Create SIP Normalization script

   1. Go to Device -> device settings -> SIP normalization script

   2. Click AddNew

   3. Click Import File and upload the attached file

   4. Enter a name, such as “DiscardIncoming180Ringing”

   5. Click Save

3. Go to  Device -> Trunk

4. Find and edit SIP Trunk for Advanced Queuing

5. Within “SIP Information” section, find “Normalization Script”

6. Choose the script “DiscardIncoming180Ringing”

7. Save and Reset trunk
