You are troubleshooting an issue where SIP AST Endpoints are having trouble activating/deactivating Avaya Aura® Communication Manager (CM) features such as Call-Forward. You already know that CM sends information regarding these features over the OPTIM Trunk-Group, and this seems to be up and in-service.
If misconfigured, which related CM form could affect the CM feature information being sent to Avaya Aura® Session Manager (SM)?
