# Configuring Trunks
(Mitel Integrated Configuration Wizard)

Use this page and the next to provision trunks and their answer points.

## SIP Trunks

Although MiVoice Business supports the use of multiple SIP service providers, the wizard allows you to provision only one. You can use the System Administration Tool to add others after applying the initial configuration.

Several profiles for popular SIP service providers in the U.S, Canada, Australia , Germany and other countries are included for your use. More are available on the Software Downloads page at Mitel Online (http://portal.mitel.com).

NOTE: The Main Business Number entered on the System Parameters page is used to set up CPN substitution for SIP trunks as well BRI and PRI trunks.

To provision the system with SIP trunks:

1. Select Configure SIP Trunks.

2. Select a SIP Service Provider profile.
   Or
   Choose Custom from the list of providers and click Load file... to load a profile obtained from Mitel Online.

3. Complete the remaining fields as required. For help, click the links provided below:

   SIP Network Element Name | Same as 'System Name' in Network Elements form.
   FQDN or IP Address | Same as in Network Elements form.
   External SIP Proxy FQDN or IP Address | Same as in Network Elements form.
   Number of SIP Trunks | Same as 'Maximum Simultaneous Calls' in SIP Peer Profile form.

Other configuration data applied:

- SIP trunks assigned COS #55 and Trunk Service #9 with 'Digits to Absorb' set to '0.'

- 'Public Network Access via DPNSS' set to 'Yes' in COS of all users/services.

## Trunk Answer Points

An answer point is the voice mail message center, voice mail auto attendant, an extension. or other destination for incoming trunk calls. (See Trunk Attributes for valid destination).

When using an extension number, it can be an existing number on the system or a new one that you are adding with the wizard. If it's a new number, a 5020 IP device will be added to the system and provisioned with the number provided.

To configure the trunk answer point:

1. Select Configure Answer Point.

2. Select the desired answer point:

- Voice Mail Message Center/Voice Mail Auto Attendant: Allows external callers to leave voice messages for other system users. It also allows users to call into the system and to access their messages. This option is available when provisioning a single MiVoice Business system only.

- Voice Mail Auto-Receptionist: This option is only available for selection on platforms that have MiCollab Nupoint UM voice mail. It allows external callers to access the auto attendant and place calls to system users. Additional programming is required in the MiCollab Nupoint UM Web Console application to fully configure this option. See the MiCollab Nupoint UM Help for instructions.

- Extension Number: Enter the extension number of the answer point. If the Main Business Number is provided in the System Parameters Page, then a DID will created as the Main Business Number and the associated DN will be Extension Number of the Trunk Answer Point

3. Select a trunk type: Non-Dial in Trunks
   Trunks that carry incoming calls from the public network to a fixed answering point (console, extension or bell) in the PBX. See also Dial-in Trunks. or Dial in Trunks
   Trunks that connect incoming calls directly to an extension in the PBX without going through the operator. Also known as Direct Dial In Trunks (DDI) or Direct Inward Dial (DID). Seel also Non-dial in Trunks..

4. For Dial in trunks, select whether or not to include forwarding information in incoming calls that are forwarded to their final destination from another DN in the PBX.

## Digital and Analog Trunks (for AX and MXe platforms)

To configure digital trunks, you must have selected the T1/E1 Combo card on the Controller Modules and Framers page.

NOTE: The digital and analog trunk configuration is not applicable for EX platform.

To configure the digital and analog trunks:

1. For digital trunks, select Configure Digital Trunks.
   If the check box is cleared, all field entries are ignored.

2. For each digital trunk type, enter the number of links.
   The number of links is dependent on the programmed modules.
   Quad BRI: maximum 4 BRI links.
   Dual Framer: maximum 2 PRI links or 2 T1/D4 link (when port interfaces are T1)
   T1/E1 Combo: maximum 1 PRI link or 1 T1/D4 link (when port interface is T1)

3. Select the Protocol.

4. For analog trunks, select Configure Analog Trunks (Non-Dial In)..
   If the check box is cleared, all field entries are ignored.

5. Click Next to continue.

The Configuration Wizard configures the trunks based on trunk type.

- BRI: COS 54, COR 5 (blocked), Link Descriptor 3, Trunk Service 4, Circuit Descriptor 9, and Trunk Group 4

- T1/D4: COS 53, COR 5 (blocked), Link Descriptor 2, Trunk Service 3, Circuit Descriptor 8, and Trunk Group 3

- PRI: COS 52, COR 5 (blocked), Link Descriptor 1, Trunk Service 2, Circuit Descriptor 6 (for E1) or 7 (for T1), and Trunk Group 2

- Analog: COS 51, COR 5 (blocked), Trunk Service 1, Circuit Descriptor 4, and Trunk Group 1.

NOTES

- The Embedded ASU Unit is not supported on the AX platform. The unit number read-only and is defaulted to 2 for all supported platforms.

- All links of the same type are placed in the same trunk group. Each trunk group may contain a mix of trunk types— example, E1 PRI and TI PRI.

- BRI and PRI links must be assigned a protocol using the System Administration Tool.

## Configure Digit Modification for Incoming Calls

To provision Direct Inward Dialing the system takes digits received from the PSTN
Public Switched Telephone Network. The worldwide analog voice network accessible to all those with telephones and access privileges. and modifies them, either by removing (aborbing) digits and inserting others, to form a new number corresponding to an extension, hunt group pilot number or other call destination.

NOTE: DID is available on PowerPC (PPC) platforms
Variants of MiVoice Business that use PowerPC processors--MX, MXe, CX, CXi, and AX. See also x86 platforms. platforms only.

To set up digit modification for incoming calls:

1. Enter the number of Digits to Absorb (if any).
