3CX Phone System for Windows System for Windows
Page 22
You can configure per extension what the phone system should do if the extension does
not answer the call, is busy or is unregistered.
In the case of No Answer you have to
specify the time in seconds that you want the system to wait. In the case of busy, you
have to specify whether you want the phone or the PBX to do the busy signaling. By
default, most SIP phones do not give a busy signal back, but accept a second incoming
call. If you want to redirect a call when an extension is busy, you will need to specify “Use
PBX status” in the busy detection list box.
You have the following re-direction options;
Continue ringing – the system will do nothing.
End Call
Forward to voice mail
Forward to extension –Specify the extension to forward to in the list box.
Forward to Queue/ ring group – Specify the virtual extension number of the ring group
or Queue in the list box
Forward to Digital Receptionist –
Specify the virtual extension number of the digital
receptionist in the list box.
Forward to Outside number – In this case the system will forward the call to an
outside number. Be sure to include the complete dial string including the prefix.
The Forward all calls option is used when a user is temporarily out of the office, for
example on holiday.
