Configuration of Microsoft Components for Integration with IM and Presence Service
Line URI Configuration on Microsoft Active Directory
Before you configure the Line URI parameter on Microsoft Active Directory, note the following:
-
For the Line URI, we recommend that you use the format: tel:xxxx;phone-context=dialstring
-
xxxx also specifies the directory number that the CTI Manager reports to IM and Presence Service as the calling or called number when a call gets placed.
-
phone-context=dialstring enables the Microsoft Office Communicator client to control one of the devices that are associated with the directory number.
-
-
If you configure the device ID, the Microsoft Office Communicator client controls that particular device on initial sign in; for example: tel:xxxx;phone-context=dialstring;device=SEP0002FD3BB5C5
-
If you configure the partition, the Microsoft Office Communicator client specifies the partition for the directory number; for example: tel:xxxx;phone-context=dialstring;device=SEP0002FD3BB5C5;partition=myPartition
-
The Line URI only takes effect when the Microsoft Office Communicator user signs in.
-
After initial sign in, the Microsoft Office Communicator user can change the line appearance that they wish to control using the Phone Selection plug-in.
-
If you do not configure the device ID in the Line URI, the CTI Gateway determines the devices that are associated with the line Directory Number (DN). If only one device is associated with the line DN, the CTI Gateway uses that device.
User Authentication on IM and Presence Service
When configuring the SIP URI on Microsoft Active Directory, consider how the IM and Presence Service performs the user authentication checks. The user authentication logic is as follows:
IM and Presence Service checks if the Microsoft Office Communicator (sign in) user ID matches the Cisco Unified Communications Manager user ID. If IM and Presence Service cannot find a match:
IM and Presence Service checks if the Microsoft Office Communicator user email (the From header) matches the Cisco Unified Communications Manager user email. If IM and Presence Service cannot find a match:
IM and Presence Service checks if the Microsoft Office Communicator user email matches the ocsPrimaryAddress value of a Cisco Unified Communications Manager user.
For example, a user Joe has the Microsoft Office Communicator user ID joe@someCompany.com. The From header in the SIP INVITE is sip:joe@someCompany.com.
In this case, IM and Presence Service checks the following:
If there is a user in the Cisco Unified Communications Manager database whose user ID is ‘joe’. If this user ID does not exist:
If there is a user in the Cisco Unified Communications Manager database whose mail is ‘joe@someCompany.com’. If this mail does not exist:
If there is a user in the Cisco Unified Communications Manager database whose ocsPrimaryAddress is ‘sip:joe@someCompany.com’.
