How to remove the ringback tone for calls landing to Auto Attendant SIP trunk
Applies to:
Imagicle Advanced Queuing on Cisco UCM
Imagicle Auto Attendant on Cisco UCM
Description:
Cisco UCM plays a ringback tone for incoming calls to Imagicle services. To remove the ringback tone, a SIP Normalization Script can be implemented. The script processes any SIP messages coming from AdvQue or AutoAtt and discards any “180 Ringing” signaling.
How-to:
Log in into Cisco UCM
Create SIP Normalization script
Go to Device -> device settings -> SIP normalization script
Click AddNew
Click Import File and upload below file:
d. Enter a name, such as “DiscardIncoming180Ringing”
e. Click Save
Go to Device -> Trunk
Find and edit SIP Trunk for AdvQue
Within “SIP Information” section, find “Normalization Script”
Choose the script “DiscardIncoming180Ringing”
Save and Reset trunk
