    • Feature Key Synchronization for Do Not Disturb (DND) and Call Forward (CF)

    Note: By default, Polycom phones will be configured to synchronize the Call Forward and DND functions between the phone and the PBX. This means that if you enable either feature on a handset, the same setting will be applied to the User's Answering Rules on the PBX (and vice-versa).

    • If you would like to disable this functionality, you can do so with the following overrides. Note that you can use either of these commands individually.

    voIpProt.SIP.serverFeatureControl.cf="0"

    voIpProt.SIP.serverFeatureControl.dnd="0"

    voIpProt.SIP.serverFeatureControl.localProcessing.dnd="0"


    • up.Pagination.enabled=" "
      • 0= Disable (Default)
      • 1= Enable

    You can disable the DND (introduced as a new feature with Polycom firmware version UCS 5.1.1).

    • Disabling DND on Idle screen.
    feature.enhancedFeatureKeys.enabled="1"
    softkey.feature.doNotDisturb="0"
    
    • In order to remove the gap left by this simply add the additional:
    efk.softkey.alignleft="1"
    
    • Remove DND Softkey and Menu Option:
    feature.doNotDisturb.enable="0"
    

    Electronic Hookswitch (EHS) mode for phone's analog headset jack


    up.analogHeadsetOption=" "
    
    •  0 - No EHS-compatible headset is attached.
    •  1 -  Jabra EHS-compatible headset is attached.
    •  2 -  Plantronics EHS-compatible headset is attached.
    •  3 -  Sennheiser EHS-compatible headset is attached.

    Change default NTP server

    tcpIpApp.sntp.address="<NTP Server FQDN>"
    

    Static DNS Override

    • device.dns.serverAddress="8.8.8.8"
    • device.dns.altSrvAddress="8.8.4.4"

    Preserve Original Caller ID on Transfers

    • voIpProt.SIP.useRFC3325="1"
    • voIpProt.SIP.useRFC3325.display="1"
