NETWORKING CONSIDERATIONS FOR MICOLLAB CLIENT
The MiCollab Client Softphone 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.
UCA Version 3.1 (SDK Version 1.2) does not provide support for 3300 SIP trunking.
MiCollab Client 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, MiCollab Client supports QoS settings for voice packets.
MiCollab Client is able to use two different QoS settings. The selection of which QoS setting is
used is made in the IP Phone Emulation Settings Window.
In the IP Phone Emulation Settings Window, above the Start/Stop Phone Emulation Service
button, there is a check box called “
Use the internal QoS settings, with a fixed DSCP of 0xa0”.
If this setting is checked, MiCollab Client will use the Microsoft setting which is a DSCP value
of 40, the equivalent of a precedence of 5 for legacy TOS based routers.
If the setting is unchecked (the default setting), MiCollab Client will use the Mitel setting which
is a DSCP value of 46, and provides marking into the Expedited Forwarding queue for DSCP
based routers.
A TOS based router will work correctly with a DSCP value of 40. However, a DSCP value of
40 could give unpredictable results if used in a network that employs DSCP based routing
schemes.
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.
MIVOICE BUSINESS CONSOLE
ACCESS CONNECTIONS
The MiVoice Business Console uses a number of access connections to the MiVoice Business
(or ICP) controller.
• The MiVoice Business Console uses MiNet to communicate with the MiVoice Business for
call processing via a single IP socket.
• The MiVoice Business Console uses a proprietary CSMSG protocol to communicate with
the MiVoice Business to obtain directory information for incoming call display, phonebook
and Busy Lamp display via a single IP socket.
• The MiVoice Business Console uses Data Services to obtain configuration data from the
MiVoice Business via a single IP socket.
