Configuration and Maintenance Manual

Configure the Mitel Communications Director (MCD)

When the system platform you are using is the Mitel Communications Director (MCD), configure

it first before you enter the SIP Server Configuration information in MCA. This allows the MCD

to communicate and operate with the MCA product installed on the MAS server.

Configure the MCD as follows:

• Configure SIP Device Capabilities, below

• Configure Extended Hunt Groups on page 24

• Configure Class of Service (COS) on page 24

• Create IP Devices on page 25

• Create a Hunt Group on page 25

Configure SIP Device Capabilities

MCA is configured as a SIP extension on the MCD and allows the two to communicate. If the

SIP Session Timer times-out before the system establishes a session with MCA, the session

is torn down and the call does not complete. Configure the SIP device to prevent a scenario

where attendees may be inadvertently dropped when an outgoing call is place during a

conference.

Configure SIP Device Capabilities and set the following:

• Replace System based with Device based In-Call Features: Set to Yes.

• Session Timer: Set value to 0.

• SDP Options/Allow Device To Use Multiple Active M-lines: Set to Yes

Configure Extended Hunt Groups

It is only necessary to configure Extended Hunt Groups when more than 65 MCA User Licenses

are purchased. Configure the MCD for Extended Hunt Groups to allow you to program a hunt

group with more than 64 members.

Configure License and Option Selection, and then set Extended Hunt Group to Yes.

Configure Class of Service (COS)

Create a new COS for MCA SIP ports by modifying the default COS configuration. This COS

is assigned to the hunt group you create for MCA, see Create a Hunt Group on page 25.

Note: When selecting Extended Hunt Groups, the Hunt Group capacity of the system

changes from 176 hunt groups with a maximum of 64 members each, to 16 hunt groups

with a maximum of 240 members each. Although you can program more, only one

240-member hunt group is recommended per system.
