TALKSWITCH CONFIGURATION 89
2.4.2.4 Automatic fax detection
If a fax call is detected then:
TalkSwitch can automatically detect incoming faxes and route them to your
fax machine. To do this, the auto attendant must answer all incoming calls
and listen for the CNG tone emitted by the incoming fax call. If a CNG tone is
detected within nine seconds, the call is identified as a fax. If no CNG tone is
detected, the auto attendant will wait for the caller to dial the appropriate
digits or hang up.
If you do not want to use fax detection, have the unit perform no action.
If you want automatic fax detection, configure your incoming fax line to
route faxes to extension 118. The default configuration assumes that your
fax machine is attached to extension 118 (113 for units with four extension
jacks).
2.4.2.5 No selection was made at the auto attendant
After the auto attendant has finished playing and no selection was made
within a specified number of seconds, the unit can route the call to any
extension including a fax machine, play an auto attendant or
announcement, go to a voice mailbox, go to the dial-by-name directory,
queue to a ring group or simply hang up.
2.4.2.6 Additional features at the auto attendant
The digits 6, 7, 8 and 9 are not available as programmable options. They are
used for other system features.
If 6 is dialed
If you press 6 at the auto attendant, you are able to configure and use
auto call back and prompted call back features. See 2.5 Call Back/Call
Bridge on page 102 for more details about configuring call back and
3.11.2 Using call back on page 152 for details on using call back.
Some older fax machines do not emit a CNG tone and the auto attendant
cannot detect them as an incoming fax. Also, if your auto attendant
volume is set too high, or if your incoming telephone lines are noisy, the
auto attendant may not be able to detect the incoming CNG tone.
