Hunt Groups - Hunt Groups enable incoming calls to be directed to a group of users. The call route is based on a number of factors, including first available, longest idle, broadcast hunting, and circular hunting.
A hunt group works in conjunction with route filters and hunt lists to direct calls to specific devices. If a phone or device is ringing and not being answered, then another available number is searched for until the call is answered.
A hunt list contains a set of line groups in a specific order. A single line group can appear in multiple hunt lists. A line group comprises a group of directory numbers in a specific order. The order controls the progress of the search for available directory numbers for incoming calls.
Call Pickup - Call Pickup allows users to pick up incoming calls from their own group. Group Call Pickup and Directed Call Pickup allow users to pick up incoming calls to another group or individual, respectively.
Directory numbers are assigned to call pickup groups and Cisco Unified Communications Manager automatically dials the appropriate call pickup group number. Users select Pickup to answer the call.
Call pickup - allows users to pick up incoming calls from their own group.
Group call pickup - allows users to pick up incoming calls from another group.
Other group pickup - allows users to pick up incoming calls from a group that is associated with their group. You cannot use this option with the hunt group feature.
Directed call pickup - allows users to pick up an incoming call on a directory number. You cannot use this option with the hunt group feature.
Personal Ringtones - Users can select a ringtone for incoming calls from a menu of distinctive ringtones for their client in the Options menu.
Do Not Disturb - When presence is set to Do Not Disturb, no ringer and no visual call notification will show and the call will appear as a missed call in the call history.
Call Statistics - Users can view real-time statistics when on a call. They can view audio, video, and screen share statistics.
Ring on all Devices - Users can hear incoming calls and alerts on their computer speakers and all connected devices. Even if their headphones are plugged in, when they receive a call or IM alert, the sound is played in both the headset and through the computer speakers. This feature is enabled by default, but users can change their ringer and alert preferences in the Options menu.
Mute Before Answer - When joining a call, the user can mute their phone before connecting to the call.
Audio Device Selection - Users can select their preferred headset or other audio device directly from chat windows. A new option allows users to open audio options and select their microphone, headset, and ringer preferences.
Click to Call for Office 2013 (32 bit) - Support call capabilities for Office 2013 applications.
HD Audio with G722 wideband codec - The G.722 wideband audio codec is introduced to deliver a superior call experience to the user.
Native Support for Accessories - users can use Jabra, Logitech, Plantronics, or Sennheiser accessories to answer, mute, end call directly from the devices.
Self View - Users can move and resize the self-view window on video calls.
SAML based Single Sign On - Security Assertion Markup Language (SAML) is an XML-based open standard data format that enables you to access a defined set of Cisco services seamlessly after verifying credentials with an Identity Provider. You enable SAML SSO in Cisco WebEx Messenger Services, Cisco Unified Communications Manager, or Cisco Unity Connection.
Custom Tabs - Users can create custom tabs.

Directory integration with OpenLDAP requires you to define specific parameters in a Cisco UC Integration for Microsoft Lync configuration file. See LDAP Directory Servers for more information.
Cisco UC Integration for Microsoft Lync requires Microsoft Internet Explorer 8.0 or later. The application uses the Microsoft Internet Explorer rendering engine to display HTML content.
Cisco UC Integration for Microsoft Lync integrates with Microsoft Lync for IM and Presence and with Microsoft Outlook and Microsoft Office applications for Click to Call on the client side only. Cisco UC Integration with Microsoft Lync is therefore compatible with all of the same versions of Microsoft Lync, Outlook, and Office applications whether they are Office 365-based or traditional on-premise deployments.
Cisco UC Integration for Microsoft Lync sends Internet Control Message Protocol (ICMP) requests to the TFTP server. These requests enable the client to determine if it can connect to Cisco Unified Communications Manager. You must configure firewall settings to allow ICMP requests from the client. If your firewall does not allow ICMP requests, the application cannot establish a connection to Cisco Unified Communications Manager.
Cisco UC Integration for Microsoft Lync uses the ports and protocols listed in the following table. If you plan to deploy a firewall between the application and a server, configure the firewall to allow these ports and protocols.
Port | Protocol | Description |
---|---|---|
Inbound | ||
16384 to 32766 | UDP | Receives Real-Time Transport Protocol (RTP) media streams for audio and video. You set these ports in Cisco Unified Communications Manager. |

This section contains information about known limitations and restrictions.
The following known issue applies to the current version of the software:
When the presence state is set to Do not Disturb in Microsoft Lync, the Cisco UC Integration for Microsoft Lync client will not have audio (ringer) or visual (call notification alert) notifications. The notifications can be configured by either the administrator or the user. The call will appear as a missed call in the call history
Setting the presence in Microsoft Lync to Do not Disturb will not currently set a deskphone to DND. This will be available in a future release.
Installing Cisco UC Integration for Microsoft Lync and Cisco Jabber applications, or other third party Unified Communications applications, on the same machine may result in unexpected behavior in the client and is not recommended.
Users with upper ACSII characters in their usernames or passwords is supported in Cisco Unified Communications Manager 9.1(2) or later, or users must use lower ASCII characters for their username and passwords for earlier versions. The Cisco Jabber for Windows softphone fails to register with Cisco Unified Communications Manager when users enter some special characters such as ü, ä, or ö in the username or password. The user receives the following error message: “Invalid username or password entered. Go to Phone Services in the Options window and enter the correct username and password".
The following rules apply to space characters and credentials:
Cisco Medianet Metadata is no longer supported in Cisco UC Integration for Microsoft Lync.
When configuring SAML SSO on Cisco Unified Communications Manager and Unity Connection servers, you must use a fully qualified domain name (FQDN) instead of an IP Address to define the server name. If you use an IP Address, the client displays a warning message that the certificate is not valid. The requirement to use an FQDN is because the embedded Internet Explorer browser is not able to validate IP addresses in the Subject Alternate Name (SAN) certificate.
The client can store up to 250 entries in your call history.
If you use Plantronics accessories for Cisco Jabber call management, Plantronics Hub 3.5 is required. Download Plantronics Hub 3.5 from the Plantronics website.
The client cannot play broadcast voice messages.
You must enter descriptions for each device if Cisco UC Integration for Microsoft Lync users have multiple deskphone devices of the same model. Cisco UC Integration for Microsoft Lync displays these descriptions to users so that they can distinguish between multiple deskphone devices. If you do not enter descriptions, the client displays the model name of the device and users cannot distinguish between various devices of the same model.
Cisco UC Integration for Microsoft Lync does not currently support CTI connections over transport layer security (TLS). As a result, Cisco UC Integration for Microsoft Lync users cannot switch from using a CSF device to using a desk phone device if they belong to the Standard CTI Secure Connection user group.
Software phones (CSF devices) are not supported in virtual environments. Use Cisco Virtualization Experience Media Engine (VXME) for Cisco UC Integration for Microsoft Lync call capabilities in a virtual environment.
Cisco UC Integration for Microsoft Lync does not currently support Check Point VPN.
When using Expressway Mobile and Remote Access to connect to services from outside the corporate firewall, the client does not support the following capabilities:
If users select Use my phone for calls in their client to enable deskphone mode, then they must log in or logout of their hunt groups using the deskphone. If users are in deskphone mode, then the Log Into Hunt Groups option in the Cisco UC Integration for Microsoft Lync client becomes disabled.
If you enable the Legacy Immediate Divert option in Cisco Unified Communications Manager, users cannot decline calls when they are logged into Hunt Group in softphone mode, but can decline calls in deskphone mode. To disable users to decline Hunt Group calls in both softphone and deskphone mode, you must enable the parameter preventdeclineonhuntcall in the configuration file.
If the options for Calling Party Information and Called Party Information are disabled in Cisco Unified Communications Manager, then users logged into Call Pickup in softphone mode do not see either calling party or called party information displayed in the call alert notification. However, if those options are disabled and users log into Call Pickup in deskphone mode, then calling party or called party information is still displayed in the alert.
If you select the Audio only notification on Cisco Unified Communications Manager and the user is on a call, then the user does not hear any sound indicating that there is a call to pick up.
If users select Pickup on their deskphone when in Deskphone Mode, a conversation window is displayed momentarily.
The pickup notification alert only displays a maximum of 23 characters.
Hosted photos cannot be displayed in Cisco UC Integration for Microsoft Lync due to an issue supporting authenticated proxies, even if the server is listed in the Bypass setting. .
Users may experience resolution issues when using Cisco UC Integration for Microsoft Lync to make a call with a Lifesize Express 220 endpoint. If the user puts the call on hold, then after resuming the call the send and receive video resolutions on the Cisco UC Integration for Microsoft Lync end is greatly reduced.
The following rules apply to space characters and credentials in on-premises deployment scenarios:
