- 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
