How can this problem be fixed?

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?
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 the correct CLID.
