Limitations and Important Considerations

General Limitations

The following limitations and considerations apply to all releases:

  • Users need to supply non-blank values of all servers, even if they are not required for that particular phone mode. For example, in soft phone mode, user must enter a non-null string value in preference page configuration for phone functionality.
  • For Dial Rules to function properly with Cisco UC Integration for IBM Sametime and Cisco Unified Communications Manager prior to Release 8.6(2), an additional .cop file must be installed on the version each time dial rules are added or modified.
  • Use of multiple Sametime community servers:
    • The phone, presence and voicemail functionality in Cisco UC Integration for IBM Sametime only function when the user logs in to their default community. However, the simultaneous use of other communities (in other words, if the user logs in and out of other community servers) does not impact Integration functionality as long as the default community is connected.
    • Impact: Customers who do not log in to the default community, but instead log in to another non-default Sametime community server will not be able to use Integration features.

9.5 Limitations

The following limitations and considerations apply to the 9.5 release:

General Limitations

  • There is an issue with a call that moves from "Integrated" to "Standalone". This is a case that involves three parties: A, B, and C. A makes a call to B, and B then transfers the call to C. Subsequently, C transfers the call back to Party B.
    • Issue: After the transfers complete, A first sees the number of C in the call area of the chat window (the chat between A and B). The call then pops out to a standalone window that shows the name and image of B.
    • Impact: When this occurs, the user must click the pop-in (View video in Chat window) button on the standalone window to return to the integrated call display.
  • Delay in window swap operations for video calls: Cisco UC Integration for IBM Sametime allow you to switch between various window types, such as to full screen from an integrated conversation window, or to a conference window from a standalone conversation window. Because video GUI elements are moved on the screen, a slight, perceptible delay occurs during this operation.
  • If a user has not set up a voicemail profile, then an incoming call alert will not include a Decline button on their computer, because the call cannot be diverted to voicemail. In this scenario, the only options for the user on an incoming call are to answer the call or manually mute the ringer. The future release(s) will implement muting of incoming call ring-out.
  • The conference participant list is not updated in the Cisco UC Integration for IBM Sametime GUI when the conference call is in the locally HELD state.
  • Sometimes, addition of an existing call to an existing ad hoc conference fails because of network race conditions. In this circumstance, Cisco UC Integration for IBM Sametime does not repeat the "add to conference" operation attempt; instead, the user can attempt the operation manually as desired.
  • Desk phone video operation requires that the Medianet service is installed and running before the Sametime client is started.
  • Sometimes, if a desk phone video call is escalated to a video conference or merged with another video call, the resulting local call is in audio-only mode. However, the user can escalate that call back to video after a hold-and-resume operation
  • De-escalating a desk phone video call in Cisco UC Integration for IBM Sametime results in cessation of both video transmission and reception (this is unlike soft phone mode, in which the remote video can still be received).
  • When the user switches from soft phone mode to desk phone mode (audio and video) for the first time, the Integration shows the configured device names. However, this listing does not include the line numbers associated with the devices. Because of this, a user that changes to desk phone mode will not be able to designate the specific line number. However after the transition to desk phone mode completes, the line numbers will be visible and user can switch between them.


    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.

  • The simultaneous merge of a call at both ends is not supported. If you attempt this procedure, you could encounter unexpected results. For example, some calls might remain "unmerged" outside the conference, or more than one conference window might open. Similar behavior can also occur if you attempt a normal merge during slow network conditions.
  • A user who does not appear in the Contact list might get resolved to a person with name appended with the search base. This works properly for users in buddy contact list
  • If a video-enabled desk phone (whose camera is temporarily detached), is being controlled by Cisco UC Integration for IBM Sametime, any attempt to initiate a video call will result in a self-view window with a black background.
  • The Click to Call feature only supports 32-bit versions of Microsoft Office 2010 applications.
  • Persistence of an established Cisco UC Integration for IBM Sametime call is not supported across a Cisco Unified Communications Manager failover.
  • The feature that allows you to forward a voice message as an attachment will only function if the default mail client is Lotus Notes. Also, the Forward feature is not active until one minute after the user logs in to voicemail.
  • While using the conference feature in desk phone mode, the remove participant option has no effect.
  • Cisco UC Integration for IBM Sametime does not allow more than one simultaneous call to same end party number. This case holds even when first call is on hold.
  • If a number that is not configured in LDAP is added to the conference window using the search bar, that participant will be added as number only, and will not be resolved as a name that is configured on Cisco Unified Communications Manager.
  • Desk phones that use a SIP-based protocol might experience one-way video during a desk phone video call. This behavior occurred on Cisco 9XXX series devices in lab tests.
  • Some text strings on the Call Voicemail button and in the Preference windows are truncated when Cisco UC Integration is used with some non-English languages.

Desk Phone Video Limitations

  • 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.
  • 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.
  • 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.
