Release and General Information


Enhanced Unified Communications

Cisco UC Integration(TM) for IBM Sametime provides instant access to Cisco Unified Communications capabilities directly from IBM Sametime. The integration enhances productivity by extending native audio and HD video capabilities to Sametime IM and presence users. It also includes Cisco phone control and presence status with integrated voicemail and conversation history. The integration allows access to Cisco call control for both standalone and Notes-embedded clients.

Features and Capabilities

With this tight integration for IBM Sametime, users get a consistent user experience, enhanced communications capabilities, and reduced infrastructure complexity. The integration also provides Sametime users with the following capabilities:

  • Native phone mode control for audio and video Users can choose to control audio or video calls in IBM Sametime from the user's computer or from the phone.
  • Phone presence and control using XMPP The phone presence icon, which indicates whether a contact is busy on another call or available to receive a call, is displayed in addition to the IM presence icon where available.
  • Click-to-call capability from IBM Sametime client Place calls from your list of existing contacts by right-clicking a contact and selecting Phone Call or by choosing a number from the provided options.
  • Integrated visual voicemail and conversation history Sametime users can view, play, or review conversation history right from the main Sametime client window.
  • Enhanced collaboration Easy creation and management of audio and video conferences by dragging and dropping contacts from the list or by searching for participants in the embedded search bar.

Limitations and Important Considerations

9.1 Limitations

The following limitations and considerations apply to 9.1 releases:

General Limitations

  • The phone status feature algorithm is time-staggered algorithm, which results in a trickle-down effect of phone status display for first few runs of the client.
  • In the case when a user does not have a voicemail profile configured, the incoming call alert toast on computer of that user will not have Decline button, since the call cannot be diverted to voicemail. The user has no option but to either answer the call or manually mute the ringer. Future release(s) will implement muting of incoming call ring-out.
  • The conference participant list is not updated in CUCI GUI when the conference call is in locally HELD state.
  • Desk phone video operation requires that the Cisco Medianet service is installed and running before the Sametime client is started.
  • If a desk phone video call is escalated to a video conference or merged with another video call, the resulting local call is sometimes in audio-only mode. However, the call can be escalated back to video after a hold-and-resume operation.
  • De-escalating a desk phone video call on CUCI IBM 9.1 results in the cessation of both video transmission and reception (unlike the Use my computer for calls mode, where remote video can still be received).
  • In normal Use my phone for calls mode (audio/video), when there is a mode switch for the first time from Use my computer for calls to Use my phone for calls, CUCI will be able to show the configured device names to the user. However CUCI will not be able to show the line numbers associated with them. The impact is that the user, if using the computer for calls and switching to the phone mode, will not be able to select the line number to change to. However, once this first transition to Use my phone for calls is complete, the line numbers will be visible and the user can switch between them.

Desk Phone Video Limitations


For desk phone video to function properly, it is important that the phone supports certain protocols that make it compatible for desk phone video on a tethered computer. For example, Cisco IP Phone 7960 with firmware SCCP60.8-1-2SR2 does not work, while Cisco IP Phone 7961 with firmware SCCP 41.9-2-3s works properly in desk phone video mode.

  • You cannot use desk phone video capabilities on devices if video cameras are attached to the devices, such as a Cisco Unified IP Phone 9971. You can use desk phone video capabilities if you remove video cameras from the devices.
  • You cannot use desk phone video capabilities with devices that do not support CTI.
  • It is not possible for endpoints that use SCCP to receive video only. SCCP endpoints must send and receive video. Instances where SCCP endpoints do not send video result in audio only calls.
  • 7900 series phones must use SCCP for desk phone video capabilities. 7900 series phones cannot use SIP for desk phone video capabilities.

9.0(1a) Limitations

The following general limitations and considerations apply to the 9.0(1a) release:

  • CUCI client does LDAP queries for the contact user ID and telephone number. If a customer does not add the telephone number in LDAP, presence will not work.
  • A call will separate out to a standalone window when it is transferred to a third party and then transferred back to the originator. If you open a chat window manually, you can move the call into the chat window manually.
  • The system administrator must supply non-blank values for all server configuration information even if that information is not required for a particular phone mode.
  • Phone status, phone, and voicemail functionality is aligned with the user logging into the default community. The use of other communities does not affect this functionality but the user must be logged into the default community. Logging out of the default community will disrupt phone status, phone, and voicemail functionality.
  • Users may notice a delay during video calls when moving between window types. Movement between window types can include moving from an integrated to standalone window and moving from a standalone call window to a conference call window.
  • It takes multiple steps to get the video in an integrated conversation window taller. First shrink the incoming chat area and then shrink the outgoing chat area. Then you can stretch you chat window so that the video fits better. You can also move the call out of the integrated chat window into a standalone window and resize that window.
  • Directory Lookup Rules do not work with Cisco Unified Communications Manager prior to Release 8.6(2). This may cause Cisco UC Integration (TM) with IBM Sametime to be unable to map incoming phone calls and voice messages to your Sametime contacts.
  • Run the configuration tool first to deploy as Lotus Notes widgets. Make a copy of the update site and ensure that only one feature jar is in each update site feature directory. Next, make two widgets, one for phone feature and one for the voicemail feature.
