NuPoint-UM Configuration

Configure VPIM

VPIM configuration consists of the following steps (described in detail below):

1. Configure basic VPIM parameters.

2. Configure the NTA table.

3. Configure the DTA table.

4. Configure the Dial Plan.

5. Configure the Network Queue.

6. Configure SMTP Message Reception.

7. Generate and verify the Alias File.

8. Test the VPIM Feature

Configure Basic VPIM Parameters

To use the VPIM optional feature, configure as follows:

1. Add any necessary optional feature software.

2. Set up Unified TCP/IP:

   • From the console Main menu, select (S) System Maintenance, (R) Reconfiguration, (R) Reconfigure System, (G) Offline Menu, (B) Duplicate Configuration, and then (U) Unified TCP/IP

   • Select (M) Configure a Module

   • Select (V) Smart Host Domain Name and enter the fully qualified domain name for the smart host (i.e. the company e-mail server).

3. Set the Features Class of Service (FCOS). By default, the FCOS is 1, which includes permissions to receive/create/send VPIM messages.

4. Set the Network Class of Service (NCOS). Use the NCOS function to control a user's privileges, such as answering, making, or giving voice messages across the network. To include basic VPIM message capability in any mailbox, set up an NCOS with NCOS bits 2 through 9 as shown here:

Configure the NTA table

For the node for each server, determine these NTA parameters:

• Node number A number, from 2 to 8191, that identifies a particular node in the system. Do not use 1 for any VPIM node.

• Protocol V for VPIM

• Access Y for all nodes

• Domain name The Internet address, up to 255 alphanumeric characters

• Prefix Type Select the prefix type for the node:

  • D, default: the VPIM user mailbox uses the prefix configured in the DTA table

  • N, no prefix: the VPIM user mailbox does not include a prefix

  • A, alternate prefix: the VPIM network uses the prefix configured in the NTA table for transporting the message between nodes in the network

• Alternate Prefix The number, from 1 to 999,999, that is the alternate prefix if the Prefix Type is set to A.

To configure the NTA table:

1. From the Main menu, select (S) System Maintenance, (W) Network Menu, (M) Network Maintenance, and then (T) Network Node Table.

2. Select (C) Create new node entry and then, when prompted, set the following parameters:

3. Node number: enter the number that identifies the node in the system.

4. Protocol: enter V (VPIM Node)

5. Domain Name: enter the fully qualified host name of the node, up to 255 characters.

6. Encoding type: enter G. (G.726 (formerly G.721) for VPIM-compliant communication)

7. Select prefix to use: enter N (no prefix should be sent from the server)

8. Access, enter Y. (allow access)

9. Press Enter to return to the Network Node Access Table Maintenance menu.

Here is a sample Node Access Table Report that includes VPIM node #3 with the address "load.bayptin.com":

Press any key to continue....

Note: The G.721 codec has been superceded by G.726, which is the standard codec for VPIM to use.

Configure the DTA table

For each node, determine these DTA parameters:

• Node Number A number, from 2 to 8191, that identifies a particular node in the system. Do not use 1 for any VPIM node.

• Absorb digit The number of digits to absorb (strip from the telephone number) for a destination node. Set this to the same length as the prefix.

• Prefix The number, from 1 to 99,999,999,999 that is the valid prefix for this node.

To configure the DTA table:

1. From the Main menu, select (S) System Maintenance, (W) Network Menu, (M) Network Maintenance, and then (D) Digits Translation.

2. Select (C) Create new prefix/node pairsand enter thenumber for the VPIM node.

3. At the Absorb digits prompt, enter the number of digits to strip from the telephone number.

4. At the Prefix prompt, enter the prefix number for this node.

5. Exit to the Digits Translation menu and select (L) List the data table to check your information. A sample DTA table is shown here:

In this example, the prefix "520" represents remote mailboxes that have 4 digits and leading digits 520. A message sent to 5202000 has a sender address that looks something like "2000@company.mitel.com. The 520 prefix is stripped as indicated by the Absorb Count of 3.

Configure the Dialing Plan

For more information, see About Dialing Plans.

• Each position or index in the Dial Plan reading left to right corresponds to a digit from 1-9 as shown below.

• The "N" indicates that the corresponding dialing plan entry represents a Network node (that is, VPIM). In the example above, the prefix for a remote office is “612” and the mailboxes are of 5 digits in length.

The “N8” placed at index number 6 indicates that all Network mailboxes starting with the digit "6" are considered remote network mailboxes with length of 8 digits. For example, when a NuPoint UM user forwards a voice mail message to mailbox 12345, that is located on the remote location Voice Mail 612, the NP-UM user enters 61212345 to send to the remote VPIM mailbox.

To configure the Dialing Plan:

1. From the Main Menu, select (S) System maintenance, (R) Reconfiguration, (R) Reconfigure system, (E) Modify Active Configuration, (M) Modify Application, (D) Dialing Plan Menu.

2. Modify the dialing plan to handle your node prefix plus the length of the mailboxes. You must set the dialing plan of every line group from which users will be allowed to send network messages.

3. Exit the active configuration menu.

Configure the Network Queue

The network queue parameters affect how NP Net and VPIM perform in a system. Use these settings, rather than the defaults, for optimum VPIM performance:

To configure network queueing:

1. From the Main menu, select (S) System Maintenance, (W) Network Menu, (M) Network Maintenance, then (Q) Modify Network Queueing.

2. Set the Network Queue Time Windows for weekdays and weekends according to the guidelines for the site. For details about the Network Queue parameters, see the NP Net topic Configure the Network Queues.

Configuring SMTP Message Reception

SMTP Message Reception must be modified to set the SMTP Receive Tasks Limit to 1. This allows the server to continue processing other calls.

1. From the Main menu, select (S) System Maintenance, (W) Network Menu, (M) Network Maintenance, (V) SMTP Receive Configuration, and then (M) Modify VPIM configuration.

2. At the Max Number of Receivers prompt, enter 1.

Generating and Verifying the Alias File

To generate the alias file:

1. From the Main menu, select (S) System Maintenance, (W) Network Menu, (M) Network Maintenance, (V) SMTP Receive Configuration, then (G) Generate Alias File. The utility automatically creates the list of prefixes with mailbox numbers that can send and receive VPIM messages.

2. Select (V) View Alias File and verify that all mailboxes are included. A sample alias list is shown here:

Each time you create or delete a mailbox with VPIM privileges, you must regenerate the alias file.

Test the VPIM Feature

When all parameters are configured and the nodes are connected, check that messages move successfully between remote mailboxes.

1. Make and send one or more messages from a mailbox on one node to mailboxes on each other node in the system.

2. Check that all messages arrived.

3. Answer each message from within the mailbox.

4. Check that each answer arrived at the originating mailbox.
