| + | Once detected the incoming fax should be routed to the ''Autosense FAX Extension'', where IAXModem will answer and pass the fax to Hylafax. |
| + | |
| + | Outgoing faxes emailed to 'user@0123987654.fax' will be sent by Hylafax to IAXModem with a dial string prefixed by 95, for example 950123987654. This will initiate a call in asterisk. The 95 prefix will be recognised as the fax route and the call passed to the relevant outgoing Trunk, where the 95 is stripped off and the real number dialled. |
