Introduction

The below document explains on the setup and configuration of simultaneous ring (simring) between a Mitel extension and a Microsoft Lync enterprise voice user. Before beginning the steps below to configure simring you will need to have previously setup a sip trunk from the Mitel MCD to Lync Server 2013 as per Direct SIP Integration between Mitel Communications Director (MCD) and Microsoft Lync Server 2013.

To enable simring from a Mitel extension to Microsoft Lync, the configuration below assumes your Microsoft Lync Enterprise voice users have been setup and configured, the configuration shown is all completed on the Mitel MCD.

User and Device Configuration

We need to create a virtual extension on the MCD and associate the Lync Enterprise voice number to it so that when someone dials the virtual extension the call is then sent over to the Lync Enterprise voice number.

From the left hand menu click on Users and Devices -> User and Device Configuration -> Click Add, Select Default user and Device.Configure the Profile tab as per the below:

User Profile:

· Last Name: Provide a meaningful last name

· First Name: Provide a meaningful first name

Service Profile:

· Number: Enter a unused extension number

· Hot Desking User: Check the box

· Preferred Set: automatically changes to No Device

Personal Ring Group

Personal Ring Groups (PRG) are an association of two or more devices for a single user under a common Directory Number (DN). The devices ring simultaneously (Ring All) when called. The typical scenario is a person’s desktop phone, Lync Enterprise Voice number, cell phone etc are twinned together, where the desk phone is considered the primary extension, which is referred to as the pilot number or prime member. Other group members are referred to as non-prime members.

From the left hand menu click on Users and Devices -> Group Programming -> Personal Ring Groups

We are going to create a PRG for extension 1001 in our configuration and then associate the Lync Enterprise voice virtual extension to it. Click Add.

Personal Ring Group: Enter the primary extension number (DN) you want to simultaneously ring. Click Save.

Next we are going to associate the virtual extension number as a member of this new PRG. Personal Ring Group Members click Add Member

· Number: Enter the virtual extension number you created above in users and devices.

· Presence: Ensure that Present is selected , if you select absent it will not simring the Lync Enterprise Voice Extension

· Click Save
