        Cisco Unified Video Camera firmware

        The Cisco Unified Video Camera is supported on Cisco Unified Communications Manager Release 7.1(5) and later.

        Important Notes

        This section contains important information to consider with the Cisco Unified IP Phone 8961, 9951, and 9971.

        Cisco Unified IP Phone 9971 and Personal Address Book or Fast Dial features

        Users of the Personal Address Book or Fast Dial feature may receive an error message followed by a request to log back into the network. In DNS round robin configurations, the phone does not retain access with the same IP address. In this situation, the phone displays a message to indicate that the user must log into the phone again.

        Plantronics Audio 615M Headset and Cisco Unified IP Phone 8961

        The Plantronics Audio 615M headset is not compatible with the Cisco Unified IP Phone 8961. You must use an alternate headset type for this IP phone. For more information, see CSCth71104.

        Plantronics CS50 USB Headset and Cisco Unified IP Color Key Expansion Module

        The Plantronics CS50 USB headset causes the phone to request power from the switch even though the headset is self powered. In this case, if a device such as a camera or expansion module is connected and active on the phone, the switch will reject the power request for the headset because the power budget has been exceeded. In this case, the headset cannot be used.

        Cisco Unified IP Phones 9951 and 9971 one-way video calls

        Because of limitations in the H.264 video signaling standards, Cisco Unified IP Phones 9951 and 9971 may not correctly display video that is received from devices supporting resolutions greater than 640 x 480. In this case, the user sees a black video screen.

        To ensure that video from such devices displays properly on the IP phone, configure high definition phones and Cisco Unified IP Phones 8961, 9951, and 9971 into different call regions and limit the video bandwidth to 384 kb/s when calling between regions.

        Cisco Virtualization Experience Client 2100

        The Cisco Virtualization Experience Client (VXC) 2100 Series are zero clients designed to deliver a user desktop from a centralized host server, providing access to desktop applications as if they were available locally. The Cisco VXC 2100 series attaches to the Cisco Unified IP Phone 8961, 9951, and 9971 through a spine connector cable.

        When running VXC with a single-tunnel option, high traffic to or from VXC may affect the phone's performance. Cisco Unified IP Phones 8961, 9951 and 9971 support 384kbps throughput bandwidth for VXC.

        Set VPN MTU to 1406 to reduce packet reassemble in Cisco Unified IP Phones 8961, 9951 and 9971, to improve bandwidth in limited packet rate.

        Video and audio applications may not play smoothly through VXC, even on a device plugged directly into a LAN.

        USB CD-ROMs and other USB storage devices have limited support. In the current VXC environment, the expected performance is a low bit/transfer rate for USB storage devices and USB CD-ROMs connected to the VXC device.

        For more information, see http:/​/​www.cisco.com/​en/​US/​products/​ps11499/​tsd_​products_​support_​series_​home.html.

        Multiple Text Messages

        If you send multiple text messages to 8961, 9951, and 9971 phones within a few seconds using CiscoIPPhoneExecute.xml, the phone may reply with an HTTP/1.1 503 Service Unavailable message, and the user may not receive the text message on their phone screen.

        No UDP for SIP support

        Cisco Unified IP Phones 8961, 9951, and 9971 do not support UDP for SIP. Do not configure the UDP protocol for SIP signaling on 8961, 9951, and 9971 phones.

        Secure Video Bandwidth When Calling Over VPN

        When using Cisco Unified IP Phones 8961, 9951, and 9971 for a secure video call over VPN and VXC VPN, the maximum supported bandwidth is 320 kbps.

        Turn Off VPN Before Downgrade

        The phone will go into an unregistered state if it is downgraded from a 9.3(1) load to a pre-9.2(3) load while VPN is turned on. Turn off VPN before downgrading to a pre-9.2(3) load.

        Firmware update timing

        If a firmware update occurs while phones are in use, users may experience problems with their phone, such as:

        • calls drop during a transfer
        • calls drop during conference set up

        Firmware updates during normal call activity are not affected.


        Note


        Cisco recommends that firmware updates are made during periods of inactivity. An example of a period of inactivity would be a maintenance window.
