/mcp• 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: • If SMTP authentication is configured for IMAP client and SMTP address of the sender matches a proxy address or primary SMTP address for the authenticated user. • If SMTP authentication is not configured for the IMAP client and the SMTP address of the sender matches a proxy address or primary SMTP address for any Unity Connection user. Following are the types of recipient based on which Unity Connection processes the messages for each individual: • If the recipient maps to a VPIM contact, Unity Connection converts the message into a VPIM message, removing any attachment that is not allowed by the VPIM standard. Unity Connection either delivers the message to the specified VPIM location if the VPIM location is homed on the local server, or forwards it to another digitally networked Unity Connection server for delivery if the VPIM location is homed on that server. For more information on VPIM, see the Networking Guide for Cisco Unity Connection, Release 15, available at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/15/networking/ guide/b_15cucnetx.html. • If the recipient maps to a user homed on the local server, Unity Connection performs the action specified on the Message Actions page of the profile for the user in Cisco Unity Connection Administration. For each type of message (voice, email, fax, or delivery receipt) you can configure whether the message is accepted and placed in the user mailbox on the Unity Connection server, relays the message to the user at an alternate SMTP address, or rejects the message and generates a non delivery receipt (NDR).
