connections on the first available port in the range from 49500 to 49549. (Usually 49500 unless
other Data Services apps are running on the same PC.)
Ports 9000 and 9002 are used by the legacy 5550 IP Console application only. The
MiVoice Business Console uses ports in the 50000 to 50511 range.
With extended capabilities of the E2T on certain 3300 ICP it is recommended that the full RTP
port range of 50000-50511 now be opened up. A particular controller may not use this full range,
but other devices such as the phones may. This makes the setting for all devices common.
New ports for this release are:
• Port 6543: This is an existing port that has been included into the table of ports. It is specific
to the NSU units and used to provide upgrade via a direct PC connection.
• Port 5320: Used by MiVoice Business to communicate with Mitel Open Integration Gateway
(OIG), Live Business Gateway (LBG), and MiTAI.
The following diagrams highlight the connections to and from the 3300 based on the above
port information as well as IP-Phone connections. The following key is used to identify the
connections:
• Arrow direction shows initial connection direction. Arrow head points to server.
• A double ended arrow means that connection is, or may be, established in both directions;
i.e. an end device might be both a client and a server.
• Description above the line is the destination (server) termination point.
• Description below the line is the source (client) origination point.
• No description on the connection implies that any acceptable port may be used, typically
within the ephemeral range, which may be defined on a particular device, but typically in
the range 1024 to 65535.
