Subject: [asterisk-users] Fax detection on SIP channel


Is there a built-in way of detecting fax tones, or a switch to T.38 on a SIP channel? I need to periodically check some efax servers for availability and figured the best way to ensure they are operational is to check for tones. I've looked into Nvdetect but the company seems to have gone out of business and I don't want to be stuck with a solution that won't make it through an upgrade of asterisk. My ITSP supports T.38 and should send a Re-Invite so is there a way to just set a channel variable when it sees this and use that as an indicator of success?

I have a sangoma card in the machine but it doesn't have any T1/E1 connections, so unless I'm mistaken I can't use the fax detection in zaptel.
