This is an Unity 5.0(1) voice mail only system that is configured with VPIM Networking to Avaya Interchange. VPIM Message Networking between the two system is working fine.
VPIM Subscriber Automatic Directory Update IS NOT Working.
Check the Voice Connector Logs and found that directory message is created and sent to the UVPIM mail box. However, new message from remote voice message system that comes into Unity did not result in a creation of new VPIM Subscriber.
Attached are Voice Connector Logs and Screen Captures.
