	Note:
	This has only been tested with Asterisk 1.4.25.1-78, Sail 2.4.1-2 and the Hylafax Contrib from Dungog smeserver-hylafax-0.9.6 with hylafax-4.4.4-1 No other asterisk implementations have been used or tested. It is assumed that you have a working Sail/asterisk installation

Sail and Asterisk Setup

General

In Global Settings make sure that 'Late Termination' is set to No. Make sure that the 'Autosense FAX Extension' is set to a number you want to use for the Fax. You will need this number later The 'Fax Delay' setting defaults to 2 seconds. You may need to adjust this later to make sure faxes get detected before asterisk attempts to terminate somewhere other than the FAX. For each of the Trunks under Trunklines that you want to be able to detect incoming Faxes on, make sure that the 'Fax' detection tick box is ticked
