Chapter 3. System Features Section 700 - OperationPage 3-30 DBS Manual - Revised April 2000 DBS-2.3/9.2-700• Once DTMF dialing is invoked, the user cannot switch back to pulsedialing without disconnecting the call.• Changing from dial pulse to DTMF is possible even if the “*” or “#” key isprogrammed for speed dialing.Hunting Priority for VAUs(CPC-AII and CPC-B Version 5.0 or higher)DescriptionThis feature allows hunting priority to be assigned to calls that overflow fromthe hunt group to the VAU. If the caller hears the VAU message and thendecides to dial back into the hunt group, he or she is placed before other callsthat have just entered the hunt group queue. For an illustration of the flow ofcalls, see Figure 2-1 on page 3-31.To further improve VAU operation, DID, DISA, and transferred calls are nowrouted to the first VAU message. (In previous releases, these calls were routedto the second VAU message.)In addition, a digital port can now be assigned as a VAU through systemprogramming. In previous releases, VAUs were assigned as standard digitalports. Using the standard digital port assignment required the installer tomake the following program changes:• The CO Offhook Signal option had to be set to “on” (FF3 1-144# 7#).• The Call Waiting Notification Tone/OHVA option had to be set to “off”(FF3 1-144# 8#).• Auto Pickup had to be set to “on” (FF3 1-144# 12#).• All FF keys for the extension port had to be cleared.The VAU assignment now eliminates the need to make these programchanges. Once a port is assigned as a VAU, the system treats that port as ifthese changes have been made.Note: Though the VAU assignment treats the VAU port as if the programsettings have been made, it does not actually change the settings. If the port islater assigned as a standard digital port, the original program settings will stillbe in effect.
