Chapter 1:
Mitel SIP Configuration for
IPCM Integration
This Document details the Mitel 3300 ICP SIP Trunk configuration when configuring to
FrontRange IPCM to enable SIP communication between the two platforms. Some detail in the screen shots below will vary based on 3300 ICP and IPCM configuration. (See notes below screen shots for these settings.)
NOTE: You will need version 9 of Mitel 3300 ICP to use SIP features.
1. Licensing
For being able to apply these settings, first you have to get a Mitel ICP 3300 number with SIP licenses enabled. Read the line SIP Trunk Licenses to see how much concurrent SIP licenses you will have for your system. In the example shown, there are two.
2. Trunking.
A SIP Trunk will be configured on the IPCM SIP Settings configuration that is pointed to the Mitel 3300 ICP server that the corresponding SIP Trunk is configured on in the following screen shots. This Trunk will provide communication and call routing from the IPCM server and will allow for prefix manipulation of the DID’s coming in and going out across the trunk.
(Refer to the FrontRange IPCM Administrators Guide for details on this configuration) The sample configuration used in this document is:
IPCM Server: IP Address: 10.0.0.56
Voice Server Ext.: 501
Outbound Call Route: 0
Outbound Internal Extension Route (applications): 5
Mitel 3300 ICP: IP Address: 10.0.0.59
Test Help Desk Extension to IPCM: 602 Live Help Desk Extension to IPCM: 604
a) Create a new network element for the IPCM server. Click on System Configuration, drop down the Voice Network Configuration folder and then select the Network Element Assignment option.
In the screen for adding a new element, put these values in the following fields, and let the others with the default value.
- Name: the one you will use, in the example is IPCM. - Type: Other
- FQDN or IP Address: The IP address of the IPCM system (in the example is 10.0.0.56)
- SIP Peer: Enable this option. Be aware that if you didn’t retrieve SIP trunks in the licensing screen, this option and the next two will be always disabled.
- SIP Peer Transport: Select the “UDP” option. - SIP Peer Port: 5060 (the one by default in IPCM).
b) Add a new SIP Peer Profile. Go to the System Configuration tree, Trunks, IP Networking/XNET, and select the SIP Peer Profile option.
Click on the Add button, and fill in these values (the others will be left as found by default)
- SIP Peer Profile Label: the label you select for the profile. In the example has the same name as the network element: IPCM.
- Drop down the combo box and select the network element defined in the previous step.
- Address type: tick the IP Address option.
- Maximum simultaneous calls: write the maximum SIP trunks retrieved on the license.
- NAT KeepAlive: enable this option.
- Disable Reliable Provisional Responses: Yes.
- FQDN or IP Address: Write the IP address of the IPCM system.
c) Not closing the SIP Peer Profile screen, go to the down frame of the screen and add as much DID Ranges as you have configured in your system (this can be seen on the System Configuration -> Trunks -> IP Networking/XNET -> DID Ranges for CPN Substitutions).
The way to do this is to add a DID Range number. In the example, the system has three ranges (configured already for the Mitel basic configuration):
d) Review the Trunk Service number you selected two steps before (b). To do this, go to System Configuration, then to Trunks, open The IP Networking/XNET folder to get to the Trunk Service Assignment option. If you selected, for example, trunk number 44 (as in the example). You should label it, and review Class of Service (also briefed as CoS). You can write the same class as in the ingoing digital trunks (BRI / PRI…), but you will have ALWAYS to avoid using CoS number 1 (this is a internal Mitel ICP 3300 restriction).
e) Configure parameters in the CoS referred in the Trunk Service used for ICPM trunk. Go to System Configuration / Trunks / Class of Service Options Assignment option, mark the CoS number you selected before, press the Change button, and be sure to check this options as affirmative:
- ANI/DNIS/ISDN Trunk Number Delivery - Calling Name Display – Internal – OMS - Calling Number Display – Internal – OMS - Display ANI/ISDN Calling Number Only - Display ANI/DNIS/ISDN Calling/Called Number - Display Caller ID on multicall / keylines - Public Network Access via DPNSS
- Public Network to Public Network Connection Allowed.
3. Call Handling
After receiving a call in your Mitel ICP 3300 System, you can send it to the ICPM system, to be handled by the second one. There are some things to be configured on this point:
a) Define a route to the SIP Trunk. In the Mitel ICP 3300 Web interface, check the System Administration tree in the combo box on the upper left corner. Then go to the folder Automatic Route Selection (ARS), and select the Route Assignment option.
Go to one of the predefined route numbers that isn’t used, click on the Change button and put the following values:
- Routing Medium: Select the “SIP Trunk” option.
- SIP Peer Profile: Drop down and select the SIP profile configured in the early steps (almost for sure will be only one)
- CoR Group Member: Write “1”. - Digit Modification Number: 2 - Digits Before Outpulsing: 1
To configure that point, you will have to go to the System Administration -> Automatic Route Selection (ARS) -> ARS Digits Dialed Assignment.
This step is easy to understand: we are only “telling” the Mitel system that any call done to a number starting with “501” will be automatically redirected to the SIP trunk we have just configured.
Press the Add button and then fill in the next fields:
- Digits dialed: by default, IPCM connects the applications to extension numbers starting by 501, so the number written here will be 501X. The X indicates the Mitel that any number will follow the first three digits. - Number of Digits to Follow: 1.
- Termination Type: select “Route”.
- Termination Number: write the number of route configured in step (a). c) Write a rule for leading digits. Go to System Administration -> Automatic Route Selection
(ARS) -> ARS Leading Digits Assignment, add a new rule, and put these values in: - Leading Digits: 5
4. Voicemail
Once the rules for handling calls have been defined, one can make calls to the ICPM system directly from the physical phone, or also a SoftPhone. But, what can we do when the call comes from the outside?
A good solution is to create a new voicemail to get ride of the incoming call, and then pass it to the IPCM. One of the uses for voicemails is to act as numeric options of a menu, so if a voicemail is created with number 4, when a user call goes into the PBX and then starts the speech like “Welcome to SAI, if you want to contact technical staff press 1, to contact a commercial, press 2...” an so on, voicemails with the number 1, 2 and the others, are configured in the system as
Transfer Only.
Create a new Voicemail filling the next values. The others can be left by default:
- Mailbox Number: the digit you will ask the customer to press for accessing to that option.
- Name: A descriptive name for that voicemail, for example, “IPCM”.
- Extension Number: The number assigned to the main application that will get ride of the call at first.
- Mailbox Type: Transfer Only.
Chapter 2:
IPCM SIP Configuration for
Mitel Integration
The most of the work of integrating a Mitel with an IPCM is located in the first party. But some changes have to be done on IPCM to make this work.
All this changes are located in the Management Portal ( Start menu on Windows> Programs -> FrontRange Solutions --> Communications Management --> Management Portal ). Log in with the defined Admin user and password.
a) Check that server settings are correct. Click on System Configuration, SIP Soft Switch, and click on the Settings option. Check that the SIP UDP port that was configured in the first chapter, second part, section (a) is the same that the one shown here (by default: 5060).
b) Configure a Trunk in the IPCM system, to send calls done by applications or users with softphones, to extensions on the Mitel or external numbers. To do that go to the System Configuration screen and open the SIP Soft Switch menu on the left on the screen. Then select the Trunks/Gateways option.
Fill in the correct settings:
- ID: The ID of the PBX (by default: Mitel) - Name: A name for the trunk
- Static IP Address: The IP Address of the Mitel PBX. - Static SIP Port: 5060 by default.
- Bridge RTP: tick this option.
- Prefixes: Here we can configure how the calls can be redirected thru this trunk depending on the starting numbers. In the example, the extensions for the physical numbers are 1001, 1002 to 1020, so the leading digits for sending calls to the operators on phones can be: Prefix= 1, Cost= 1.
Note: The cost value indicates the “far away” the destination number is, so if more than one trunk routing the same prefixes, the less costing one will be chosen, unless that route is down, so an alternative can be selected. The functionality is similar to the Automatic Route Selection on the Mitel.
See that in the sample screen there is configured a route for prefix 0. That is because the calls to external numbers always start with 0, so all these calls are directly redirected to the Mitel, and then that system will handle them.
