Preferences – System DTMF Settings
Two options are available. One simply determines whether to enable the system speed dial
capability. The other relates to PIN Security requirements for users externally accessing the
ACU-5000 - for example, telephone or SIP Phone users who dial in to the system and want to
make connections to other channels User (see Section 9.3 regarding operation by remote DTMF).
Note that, for simplicity’s sake, operation by SIP phones sending IP addresses whether in-band
or not, are considered as sending DTMF.
Note also that each channel may be individually configured as to whether it will allow any
detection/operation via external DTMF. One of the possible operations is for a remote user to
request a connection to another of the ACU-5000’s channels. If this channel is configured as
PSTN, SIP, or RoIP type, the remote user will also be required to enter the remote phone number
or IP address. The Enable Speed Dial setting determines whether or not these users will be able
enter a Speed Dial rather than enter the full phone number or IP address.
Speed dials are set up by the Preferences – Speed Dials page, see Section 6.6.
Pin Security is covered in depth in the Help information provided on this page in the GUI.
The Pin Security database is set up through the System – Users page.
