Note that because menu options and parameters may vary for different Cisco Unified Communications Manager releases, see the Cisco Unified Communications Manager documentation appropriate to your release.
Cisco Unified Communications Manager User and Device Setup
Before you configure Cisco Unified Communications Manager for integration with Microsoft Lync, you need to complete the user and device configuration on Cisco Unified Communications Manager. You need to configure the phone devices, configure the users, and then associate a device with each user.
You also need to associate a line to a device, or for users of the Extension Mobility feature, to a device profile. This association forms a line appearance. When a user is associated to the device or to a device profile, the line appearance is associated to the user.
Configure the phone devices, and associate a primary extension with each device
Complete the following procedure to assign CTI device control to the application user.
Do not add devices as controlled devices to the application user because the role "Standard CTI Allow Control of All Devices" gives the application user sufficient privileges to control any Cisco Unified Communications Manager device. Adding devices as controlled devices to the application user can negatively impact Cisco Unified Communications Manager performance because Cisco Unified Communications Manager does not support a single user controlling a large number of devices in this manner.
Before You Begin
Configure an application user for the CTI gateway.
Cisco Unified Communications Manager Administration > User
Management > User Settings > Access Control Group.
Standard CTI Allow Control of All Devices.
If you are deploying an RT model of Cisco Unified IP phones,
Standard CTI Allow Control of Phones supporting Connected
Xfer and conf.
Add App Users to Group.
Select the application user that you created for the CTI Gateway.
A dial rule must be set up to strip the + prefix coming from the Lync server. If this is not done, the Cisco Unified Communications Manager will not find the Line URI and the result is a failed call attempt.
You perform the following configuration only if users are provisioned with E.164 numbers. If both users and IP phones are provisioned with E.164 numbers, then there is no need to set up an application dial rule to strip the + prefix.
