/mcp• Change the start date and time or the end date and time for future messages. (Note that the end date and time does not adjust automatically if senders change the start date and time but do not change the end date and time.) • Delete active and future messages. Changing Broadcast Message Administrator Defaults Default behavior for the Broadcast Message Administrator is controlled by settings on the System Settings > Advanced > Conversations page in Cisco Unity Connection Administration. Following are the changes you can make to the system defaults: • Retention Period: This indicates the time for which Unity Connection retains the expired broadcast messages on the server. By default, the .WAV file and any data associated with a message purges in 30 days. To change the retention period for expired broadcast messages, enter a number from one to 60 days. • Default Active Days: This indicates the number of days that a broadcast message remains active when the sender does not specify an end date and time. The default is 30 days. To change how long a message without an end date and time remains active, enter a number from zero (0) to 365 days. A value of zero (0) days means that messages that are sent without a specified end date and time remain active indefinitely. • Maximum Recording Length: This indicates the maximum length allowed for system broadcast messages. By default, senders can record messages up to 300,000 milliseconds (5 minutes) in length. To change the maximum recording length, enter a number from 60,000 (1 minute) to 36,000,000 (60 minutes) milliseconds. • Play Oldest Message First: This indicates the order in which broadcast messages are presented to users. By default, the check box is checked that plays the oldest message first. To play the newest message first, uncheck the check box. Integrated Messaging The model of messaging in which there are separate user accounts handle the voicemails and emails for a user is known as integrated messaging. The emails for a user are managed through the user mailbox on an email server and the voicemails for a user are managed through a user mailbox in Unity Connection. Unity Connection supports IMAP and SMTP protocols for integrated messaging. The SMTP protocol is used for sending messages to another users and IMAP protocol is used for retrieval of messages. SMTP Message Handling Unity Connection can receive and process SMTP messages generated by IMAP clients, for example, a voice message recorded in a Microsoft Outlook email client using ViewMail for Outlook. When an authorized IMAP client tries to send a message to Unity Connection through SMTP, the message is categorized as a voicemail, email, fax, or delivery receipt. The sender is mapped to a user and the message recipients are mapped to users or contacts by comparing the SMTP address in the message header to its list of SMTP proxy addresses. Unity Connection processes the message for each recipient under either of the given conditions: System Administration Guide 139 Messaging Changing Broadcast Message Administrator Defaults
