Networking Considerations for MiVoice Business Console
The MiVoice Business Console is an application that runs on the PC on which it is installed.
This means that the Mitel-only DHCP options (e.g. VLAN, DSCP) are not available to the
application.
The MiVoice Business Console incorporates a MiAudio softphone. For details regarding
MiAudio refer to the document called Mitel Universal SDK, Installation and Maintenance Guide
Release 1.2. As of SDK Version 1.2, MiAudio supports QoS settings for voice packets.
The selection of QoS settings is made using the MiVoice Business Console Configuration
Wizard Quality of Service settings window. By default, the MiVoice Business Console will use
the Mitel setting for voice media which is a DSCP value of 46 and TOS value of 6. The
MiVoice Business Console must be run as administrator for non-default QoS settings to take
effect.
DSCP to 802.1p mapping in the Ethernet switch should be used when VLANs are applied at
the network switch to prioritize the voice traffic at the Ethernet Layer. A DSCP value of 46 should
be used so that, in networks that employ DSCP based routing, voice priority will be maintained.
IP Sockets and Monitors
File descriptors/sockets are a primitive data type that are used for numerous software
operations. These operations can be classified into two different types: processor file access
and IP communications. The limits on some of these uses are shown in the following tables.
IP communication uses file descriptors called sockets. A socket is used to create an IP
connection for communication or control purposes between the RTC and an IP connected
device. Devices that can be IP-connected to the 3300 ICP include IP telephones, certain
peripherals, and computers acting as application servers.
All phones and applications use sockets and services within the ICP. The 3300 ICP uses
different types of sockets for IP communication/control purposes. The MiNET socket and the
MiTAI socket are used for signalling. Voice sockets are also required on the smaller controllers
where the call control (RTC) and gateway functions (E2T) have a common processor.
Every device or application that the 3300 ICP communicates with using IP has different socket
requirements. Some devices or applications will use only MiNET sockets or only MiTAI sockets;
other devices or applications will require both MiNET and MiTAI sockets. Whether sockets are
needed on a permanent or temporary basis is dependent upon the particular device or
application.
Each device or application may have a different connection path with specific requirements into
the ICP. A range of devices will load the ICP system in different ways. We strongly recommended
that you contact System/Sales Engineering when dealing with large systems and applications
near the system limits.
Note: The System Engineering Tool includes calculations for socket consumption.
