Separate Audio and Video Port Range Configuration

The Separate Audio and Video Port Range Configuration feature enables customers to improve Quality of Service (QoS) by configuring audio traffic and video traffic on different ports.

The ports are configured from one of the following Cisco Unified Communications Manager windows:

  • System > Enterprise Phone Configuration
  • Device > Device Settings > Common Phone Profile
  • Device > Phone > Phone Configuration

The existing RTP port range parameters continue to be used for audio traffic. For video traffic, two new fields in the Cisco Unified Communications Manager Administration are available:

  • Start Video RTP Port
  • Stop Video RTP Port

The following rules apply when configuring the fields:

  • Each field must contain a number between 2048 and 65535.
  • The value in the Stop Video RTP Port field must be larger than the value in the Start Video RTP Port field.
  • The difference between the Start Video RTP Port field and the Stop Video RTP Port field must be at least 16.

After the Start Video RTP Port and Stop Video RTP Port are configured, the phone uses ports within the port range for video traffic. The audio traffic continues on the port range configured in the SIP Profile for the audio RTP port.

If the audio and video port ranges overlap, the ports carry both audio and video traffic. If the video port range is not configured correctly, the phone uses the configured audio ports for both audio and video traffic.

This feature has no user impact.

The feature is supported on the following phones:

  • Cisco Unified IP Phone 8961
  • Cisco Unified IP Phone 9951
  • Cisco Unified IP Phone 9971

  • Remotely run debug commands on a phone or group of phones without logging into each device separately.
  • Collect the phone log without logging into each phone separately.
  • Troubleshoot phones by using multiple debug categories with the debugsh (debug telephony) command
With this feature, administrators set the following parameters in the Device > Device settings > Common Phone Profile, System > Enterprise Phone Configuration, or Device > Phone window:
  • Log Profile - values: Preset (default), Default, Telephony
  • Remote Log - values: Disable (default), Enable
  • Log Server - IP address (IPv4 or IPv6 address)

The Log Server address can include a port number.

  • The format for IPv4 Log Server is: address:<port>@@base=<0-7>;pfs=<0-1>.
  • The format for IPv6 Log Server is: [address]:<port>@@base=<0-7>;pfs=<0-1>.

Note


When the Serviceability feature is enabled, it impacts call quality when the phone is using Wi-fi. The system administrator should decide if the feature should be enabled.

      Limitations and Restrictions

      Caveat CSCul01945 - Http Service Failed and Returned with Host Not Found

      You may encounter a Host Not Found error message when using a HTTP service like Extension Mobility. This issue may impact Extension Mobility or other HTTP services and is due to an increased network delay.

      This issue has been resolved in Engineering Special Release 9.4(1)ES3 and the fix will be included in the next Cisco.com release, when that release becomes available.

      For additional information, see CSCul01945 on Cisco Bug Search.

      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 2100 (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 Phones 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.

      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 Cisco Unified IP Phones 8961, 9951, and 9971.

      Multiple Text Messages

      If you send multiple text messages to Cisco Unified IP Phones 8961, 9951, and 9971 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.

      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.

      Voice VLAN and IPv6 Limitation

      If the PC attached to the PC port of the phone is using IPv6, we recommend that the PC Voice LAN access be disabled. This ensures that the PC can connect to the Voice VLAN.

      Phone Limitation During SVI Change

      Cisco IP Phones use a Switch Virtual Interface (SVI) to manage VLANs. If the SVI changes and the phones require new IP addresses, some phones require a reboot so that the new IP address is used. The following phones must be rebooted in this condition:

      • Cisco Unified IP Phone 6901
      • Cisco Unified IP Phone 6911
      • Cisco Unified IP Phone 6921
      • Cisco Unified IP Phone 6941
      • Cisco Unified IP Phone 6945
      • Cisco Unified IP Phone 6961

        Unified Communications Manager Endpoints Locale Installer

        By default, Cisco IP Phones are set up for the English (United States) locale. To use the Cisco IP phones in other locales, you must install the locale-specific version of the Unified Communications Manager Endpoints Locale Installer on every Cisco Unified Communications Manager server in the cluster. The Locale Installer installs the latest translated text for the phone user interface and country-specific phone tones on your system so that they are available for the Cisco IP Phones.

        To access the Locale Installer required for a release, access http:/​/​software.cisco.com/​download/​navigator.html?mdfid=286037605&flowid=46245, navigate to your phone model, and select the Unified Communications Manager Endpoints Locale Installer link.

        For more information, see the "Locale Installer" section in the Cisco Unified Communications Operating System Administration Guide.


        Note


        The latest Locale Installer may not be immediately available; continue to check the website for updates.
