Cisco Unity 4.0(5) Engineering Special 58
Published March 10, 2006
If a subscriber logs into their mailbox and chooses to send a voice message to another subscriber, the subject line of the voice message would contain the caller id information from the initial call to Unity. For example, if a subscriber calls Unity from extension 1234 and then logs into their mailbox, the subject line of any sent voice messages would say "Message From 1234".
If the phone switch directing the initial phone call to Unity does not send any caller id information, then the subject line would simply say "Message From ".
These symptoms do not apply to voice messages send through Identified Subscriber Messaging.
Problem Description and Resolution
The root cause of the problem is that the code within method CAvConvSubSendMsg::RunStart() in would explicitly look in the NamedProps property bag for property "MailUserCallerId" and use the value associated with it in constructing the subject line. If the switch did not forward caller id information, then the value of MailUserCallerId is blank.
The resolution has been to first explicitly check for a value associated with MailUserCallerId and if none exists, then to use the value of property MailUserExtension. The latter is guaranteed to be present as that is the property used to store the ID the subscriber used to log into their mailbox. This may be their primary ID or an alternate ID, all of which may or may not be associated with an actual phone extension.

New and Changed Behavior
The subject line of a subscriber to subscriber message sent from within a mailbox will now look like the following, depending on the information available. The examples below assume a call originated from extension 1234 for subscriber John Doe who logged into his mailbox with primary id 2222:
If caller id is available: Message From 1234 (John Doe)
If no caller id is available: Message from 2222 (John Doe)
