Avaya OneCloud CCaaS Fundamentals — Question 26

When a customer calls voicemail to retrieve their messages they hear "Hello, to access your mailbox…" instead of the users named followed by "please enter your password…".
After troubleshooting you discover that the Caller ID is not being sent correctly, therefore Avaya Aura Messaging (AAM) is not able to identify the correct mailbox associated with the station number calling into AAM.
How can this problem be fixed?

Answer options

• A. Change clid-numbering 0 SAT form to send the correct CLID.
• B. Using AAM web GUI access Administration > Messaging > Telephone Integration, write a caller ID modification rule to correct the incoming CLID format.
• C. In Session Manager, configure a DigitConversionAdapter with fromto=true to update the Form header as well as the P-asserted-identity, and link it to the AAM SIP Entity.
• D. Having identified the trunk group from Avaya Aura® Communication Manager (CM) to AMM is public, change public-unknown-numbering 0 SAT form, to send

Correct answer: C

Explanation

The correct answer is C because configuring a DigitConversionAdapter in Session Manager allows for the modification of both the Form header and P-asserted-identity, which ensures the proper Caller ID format is used. Options A and B do not address the need to update the SIP headers directly, and option D is incomplete and does not provide a specific solution for the issue at hand.
