31. In Call Dialing Format
The In Call Dialing Format can be set to In-Band DTMF (Touch Tones) or RFC 2833 (Out of Band DTMF Touch Tones). In
Call dialing refers to the numbers dialed after an outbound call has been answered by the distant party. This would typically
be the numbers dialed to steer through automated attendants, voice mail, etc. If your VoIP phone system does not
automatically convert out of band DTMF to In-Band after the call is answered, set In Call Dialing Format to "Inband DTMF".
Factory Setting: RFC 2833
32. Off Hook Dialing Delay
The Off Hook Dialing Delay is the length of time a user hears simulated dial tone after picking up the handset before
they are routed to the Primary phone number in the Phone Number Database Index 0 or hear 3 beeps, depending on
the Off Hook AutoDial program option.The time is programmable from 0 to 20 seconds. Off Hook Dialing Delay time is
needed to allow visitors time after they come off-hook to then enter the tenant's apartment number (Speed Dial Number)
or their Keyless Entry Code. Factory Setting: 3 seconds
33. Off Hook AutoDial
When the Off Hook AutoDial feature is enabled, it allows visitors that do not know the tenant's apartment number
(Speed Dial Number) a way of simply going off-hook with the handset (with no additional numbers entered) and the
unit will automatically dial the Primary Phone Number stored in Phone Number Database Index 0. This could route the
call to the building manager, care taker, receptionist, etc. The Phone Mode must be set to "Auto Dialer" in order to use
this feature. When the Off Hook AutoDial feature is disabled, a user hears three beeps instead of being routed to Phone
Number Database Index 0, once the Off Hook Dialing Delay has expired. Factory Setting: Enabled
