Prolog information
Metadata
Keywords:
These preferences are used for email functions. Even if MAPI or EWS is selected, SMTP is still used for the exchange of information between voicemail servers in the same customer network.
Setting
Description
Enable MAPI/EWS
This field is used to set the method of integration with Microsoft Exchange. The fields for configuring that method are then shown.
  • None: No connection to a customer Exchange server.
  • MAPI: Select MAPI as the method of connection to the customer Exchange server. Supported for Exchange 2007.
  • EWS: Select Enterprise Web Service as the method of connection to the customer Exchange servers.

MAPI Service

These settings are shown when Enable MAPI/EWS is set to MAPI.
These preferences set the details of a Windows server onto which the Voicemail MAPI proxy has been installed. The installer for the MAPI proxy can be downloaded from the App Center pages of the voicemail server's platform menus.
Setting
Description
Address
Enter the IP address or fully qualified domain name of the server onto which the MAPI proxy has been installed.
Port
Set the address to use for connection to the MAPI client. The default is 50792.

Autodiscovery Settings

These settings are shown when Enable MAPI/EWS is set to EWS. They allow entry of the email domains in which the voicemail server should look for Exchange servers running EWS. See Exchange Server Integration.

EWS

These settings are shown when Enable MAPI/EWS is set to EWS. They set the account details required for the voicemail server to connect with the Exchange servers using EWS. See Exchange Server Integration.

SMTP Sender

These settings are used for the sending of SMTP emails. There can be multiple entries, with the entry matching the senders email address domain used or the first entry if not match occurs. The first entry in the list is also used for information exchange with other voicemail servers.
Setting
Description
Logging
If selected, SMTP logging by the server is enabled.
Server
This section is used to enter details of the SMTP server or servers to which the voicemail server sends its messages. Click on the + icon to add another entry using the settings below. The ^ and v icons can be used to adjust the order of the entries when several SMTP servers are specified.
Mail Domain
This field is used differently depending on whether it is the first entry in the list or not:
  • For the first server entry in the list: This is the default outgoing e-mail setting. It also sets the mail destination domain on which the voicemail server filters incoming messages (see below) and so is repeated on the SMTP Receiver tab.
  • Messaging Between Voicemail Servers: For messaging between voicemail servers, the first entry in the SMTP Sender list must be the one configured and used. Each server uses the SMTP server service on the same server computer as the voicemail service. For example a Windows-based server uses the SMTP e-mail provided by the IIS on the same server. The voicemail service also uses the domain set to filter incoming SMTP mails received by the SMTP server. For this to work, the domain entered should be the fully-qualified name of the server on which the voicemail server is running, for example vmpro1.example.com. Any incoming messages where the recipient mail domain is not exactly the same as the specified domain are ignored. The recipient can either by vmsyncmaster, vmsyncslave, or the name or extension of a mailbox on the voicemail server, for example Extn201@vmprocentral.example.com or 201@vmprocentral.example.com.
  • For subsequent entries: The domain specifies that these settings should be used for e-mails sent to the matching domain. The entry must be a fully-qualified name resolvable by DNS or an IP address.
Server
This specifies the IP address or fully-qualified domain name of the SMTP server to which messages are sent. Voicemail Pro supports SMTP communication over both SSL/TLS and plain text.
  • For the first server entry in the list: Where messaging between voicemail servers is being used (central, backup and or distributed servers), the first entry is used and will match the domain set above.
  • For subsequent entries: It will be the address of the e-mail server that will handle e-mails for recipients other than another voicemail server on the network.
Port Number
This is the port number on the SMTP server to which the messages are sent.
Sender (Identifier)
Note that some servers will only accept e-mails from a specific sender or sender domain. If left blank, the voicemail server will insert a sender using either the e-mail address set for the voicemail mailbox user if set or otherwise using the best matching name it can resolve from the IP Office.
Server Requires Authentication
This check box indicates whether the connection to send SMTP messages to the mail server requires authentication with that server. The authentication will typically be to the name and password of a mailbox account configured on that server.
Account Name
Sets the name to use for authentication.
Password
Set the password to use for authentication.
Use Challenge Response Authentication (Cram MD5)
If this check box is selected, the name and password are sent using Cram MD5.

SMTP Receiver

These fields are used to configure where the voicemail server should check for incoming SMTP emails.
Setting
Description
SMTP Receiver
The SMTP Receiver setting can be set to either Internal or External. The settings available vary according to that selection.
Internal
The Internal setting can be used when the voicemail server should check the appropriate account on an SMTP server for waiting messages. The server settings will be pre-populated using the entries from the SMTP Sender form. Use this option for voicemail servers running on the IP Office Application Server server.
  • Distributed/Primary/Backup Voicemail: This is the option that should be used when the voicemail server is running on an IP Office Application Server as either one of the distributed voicemail servers or as a server in a primary/backup server pairing.
Port
This is the port on which the voicemail server listens for incoming messages. The default is 25.
Domain
: This is the domain destination address for which the server will accept incoming e-mails. Note that it matches the domain set by the first server entry in the SMTP Sender tab.
  • Messaging Between Voicemail Servers: For messaging between voicemail servers, the first entry in the SMTP Sender list must be the one configured and used. Each server uses the SMTP server service on the same server computer as the voicemail service. For example a Windows-based server uses the SMTP e-mail provided by the IIS on the same server. The voicemail service also uses the domain set to filter incoming SMTP mails received by the SMTP server. For this to work, the domain entered should be the fully-qualified name of the server on which the voicemail server is running, for example vmpro1.example.com. Any incoming messages where the recipient mail domain is not exactly the same as the specified domain are ignored. The recipient can either by vmsyncmaster, vmsyncslave, or the name or extension of a mailbox on the voicemail server, for example Extn201@vmprocentral.example.com or 201@vmprocentral.example.com.
External
Use this option when the voicemail server is on a server where it co-exists with a third-party SMTP application, for example an IIS server with SMTP enabled. The External setting should be used when the voicemail server should check the mail drop folder on a local SMTP server for SMTP e-mail messages. For example, when there is an IIS server with SMTP enabled on the same server computer as the voicemail server.
Drop Folder
This sets the folder to be monitored by the STMP service for incoming emails.
Domain
This is the domain destination address for which the server will accept incoming e-mails. Note that it matches the domain set by the first server entry in the SMTP Sender tab.
