Mitel Mi Voice Border Gateway
Welcome
This Remote IP Phones Configuration Guide provides information about using your phone remotely with the Mitel® Border Gateway (MBG).
This guide covers the following topics:
- • Supporting Documentation: how to access Mitel product and technical documentation
- About Mitel Remote IP and SIP Phones: basic information about Mitel remote IP Phone, including an overview of the remote IP Phone capabilities
- Configuring Remote IP Phones: procedures to configure your Mitel or non-Mitel IP or SIP phone to work remotely using MBG
- Troubleshooting: troubleshooting information for your remote Mitel IP Phone
- Glossary: definitions of terms and acronyms found in this guide.
Warning:
The MiVoice Border Gateway solution alone is not suitable for providing reliable access to call for emergency services (for example, 911, 999 or 112). E911 support for MiVoice Border Gateway can be provided via a line interface module. For more information, see the MiVoice Border Gateway Installation and Maintenance Guide available at Mitel.com
The system administrator should note that devices that are in teleworker mode and are connected outside of the corporate firewall will not have e911 calls blocked. E911 calls placed from such devices may report an incorrect cesid, or may be outside the coverage area of the Public Service Access Point (PSAP).
E911 service is not guaranteed to teleworkers. Since a teleworker can be geographically located away from the main office, if the teleworker relocates, the system administrator must perform a manual database update to reflect the user’s location. For this reason, it is strongly recommended that you not provide e911 services to a teleworker phone.
For more information about support for Emergency Services, refer to the Resiliency Guidelines available at Mitel OnLine under MiVoice Business or 3300 ICP documentation. (See Supporting Documentation on page 2.)

Other Notes
- The list of supported devices is subject to change. Refer to the documentation that accompanies your controller to determine which IP phones, SIP phones and peripheral devices you may implement.
- After Release 7.0 of the MiVoice Border Gateway, the SX-200 is no longer supported.
- To enhance quality of service (QoS) and facilitate traffic management, MiVoice Border Gateway can be programmed to insert Differentiated Services Code Points (DSCPs) in the IP headers of voice and signaling packets. See the “Configuration Settings” topic in the MBG online help for more information.
- MBG can be configured to use specific SSL cipher suites to negotiate security settings and encrypt information for network connections. If the highest cipher suite, TLS v1.3+ very strict, is selected, the following will occur:
- 5020, 5212, 5215, 5220, 5224, 5304, 5312 and 5324 IP Phones, MiCollab Legacy Client(v7.X) and Mitel Navigator don’t support TLS v1.3+, so will default to using TCP/PSK (“pre-TLS”) for their transport protocol. (Note that 5020, 5215 and 5220 IP Phones do not support TCP/TLS under any circumstance.) These sets can only connect to the MBG with the Legacy cipher suite enabled. 5330/40 devices do not support TLS 1.2/1.3 protocol, so will no longer be able to connect if TLS v1.3+ is enabled.
- 5320, 5320e, 5330e, 5340e and 5360 IP Phones and the 5540 IP Console can continue to use TCP/TLS for their transport protocol provided that they have been upgraded to the latest firmware version (>=6.5.1.x). This firmware is included with MBG Release 12.1 Software
- 5235, 5330 and 5340 IP Phones and 5560 IPT default to using TCP/PSK (“pre-TLS”) for their transport protocol. They can no longer use TCP/TLS and will provide only partial functionality
(calls can be made but the phones will display “Application Loading” and the keys will fail to update). - MiCollab Legacy Client (7.X) MiNET softphones default to using TCP/PSK (“pre-TLS”) if anything greater than TLS v1.2+ is used. Note that MiCollab Legacy Client (v7.X) is no longer supported.
- DECT phones will no longer be able to connect.
- 5550 IP Consoles default to using TCP/PSK (“pre-TLS”) for their transport protocol. They can
no longer use TCP/TLS and will provide only partial functionality (calls can be made but the Phonebook will be inaccessible). - MiVoice Business Consoles running Release 9.0 and above will be fully functional. Earlier versions default to using TCP/PSK (“pre-TLS”) for their transport protocol. They can no longer use TCP/TLS and will provide only partial functionality (calls can be made but the Phonebook will be inaccessible).
- 69xx IP Phones will be fully functional once upgraded to the firmware included in MiVoice Border Gateway.
- The SIP-based softphone included in the legacy MiCollab client will fail to connect over TLS.
- The 5320e, 5330e, 5340e, 6905, 6910, 6915, 6920, 6930, 6940, 6970, IP phones support FQDN provided that they have been upgraded to the firmware version 6.5.
- In the first release of the 6915, 6920, 6930, 6940 IP Phones, an external LDAP server was not supported. However, once these phones are upgraded to the latest firmware version included in MiVoice Border Gateway, access to an external LDAP server is now supported. Branding, screen saver and enhanced application files for the 69xx IP Phones must be hosted on MiVoice Business or on an external server directly accessible by remote phones.
- To successfully register a Mitel 5634 Handset when MiVoice Border Gateway IP address is used, make sure the Primary and SIP Proxy IDs are left blank or have the MiVoice Border Gateway’s IP address.
For more information about Mitel MiNet/SIP Phones, refer to the appropriate User Guide available at Mitel OnLine (see Supporting Documentation on page 2).

- Password: Enter your password provided by the MBG administrator
- SIP Registrar (or “Domain”): Enter the IP address of the MBG server
SIP Proxy (if applicable): Enter the IP address of the MBG server
Note:
The MiVoice 5360 IP phone does not support SIP.
Some SIP clients, such as iOS or Android devices running Mitel UC Advanced Mobile, support multiple accounts. This enables you to configure one account for use on the internal network and another for use on the Internet.
You can choose to have MBG present a built-in Mitel certificate or a trusted third-party certificate uploaded in the MSL Web Server panel to SIP TLS connections (TCP 5061). The default is Mitel certificate.
Note:
Changing this setting breaks the trust model with the existing clients, which results in failures to connect until redeployment. Particularly, the MiCollab Client Deployment profile setting for TLS server certificate validation must match the MBG setting, such as,
If the MBG setting is “Mitel”, the deployment profile setting for TLS-server-certificate CA must be Mitel CA.
If the MBG setting is “Web server”, the deployment profile setting for TLS-server-certificate CA must be Public CA.

Configuring DHCPv6 Option 17 on a Linux Machine for IPv6 Networks
To configure DHCPv6 Option 17 on a Linux machine for IPv6 networks:
- Open a terminal and run the following command to install the isc-dhcp-server package, if not already installed: sudo apt-get install isc-dhcp-server
- Edit /etc/default/isc-dhcp-server to specify the network interfaces for the DHCP server. For example, INTERFACES=”eth0″. Separate multiple interfaces with spaces, for example, “eth0 eth1”.
- Navigate to the DHCP configuration directory and open the dhcpd6.conf file in your preferred text editor.
- Identify the data that needs to be encoded in hexadecimal. Forexample: id:ipphone.mitel.com sw_tftpaddr=[2023:f:b:2265:250:5600:8c:9314]:20001
- Use an ASCII-to-Hexadecimal conversion tool with the delimiter set to COLON [:] to convert data to hexadecimal. For example: 69:64:3A:69:70:70:68:6F:6E:65:2E:6D:69:74:65:6C:2E:63:6F:6D:3B:73:77:5F: 74:66:74:70:61:64:64:72:3D:5B:32:30:32:33:3A:66:3A:62:3A:32:32:36:35:3A: 32:35:30:3A:35:36:30:30:3A:38:63:3A:39:33:31:34:5D:3A:32:30:30:30:31
- Insert the following line into dhcpd6.conf file, replacing YOUR_HEX_CODE with the actual hexadecimal string: option dhcp6.vendor-opts
00:00:04:03:00:11:00:47:YOUR_HEX_CODE, where:- 00:00:04:03: Mitel vendor ID in hexadecimal
- 00:11: Length of the option data in hexadecimal;
- YOUR_HEX_CODE: Hexadecimal-encoded data from Step 5.
- Save the changes to dhcpd6.conf file and exit the editor.
