Two similar requirements:
1: Incoming routes/Fax section:
Add a settable delay before the system answers the call to start fax detection.
0 - 15 seconds or thereabouts.
2: Ring Groups:
Add a 'none' or 'silent' option.
Both of these are to defer or delay handling of an incoming call for a settable time.
This is to allow external equipment such as Faxes or Security systems time to act when appropriate, without ringing 'normal' extensions.
(Security systems often use a Ringback or double call system to trigger answering, so a delay is needed for them to act correctly).
By looping the 'silent ring' back to itself, this also allows a 'never ring anything' facility for such as fax (machine) lines that are never used for incoming calls but could be used as outgoing trunks when otherwise available.
[I will make an extra donation when each of these is implemented - RJ].
