[asterisk-users] Hangup conundrum with RxFAX
Heres something that's making me scratch my head... I'm using RxFAX on ISDN lines and in-general it's going well. However, there seems to be a case when the fax doesn't get delivered, but looking through the CDRs it seems that the call happened, RxFAX was executed .. time passed (1-2+ minutes) then hangup. I'm wondering if some FAX machines just hangup after the call rather than complete some sort of ending negotiation, or if the RxFAX part misses the end and just sees the hangup.. Now, in a "normal" fax machine, it's going to print the fax regardless, even if the last page is only half full because of a genuine line drop or hangup, but it seems that: [Description] RxFAX(filename[|caller][|debug]): Receives a FAX from the channel into the ... Returns -1 when the user hangs up. Returns 0 otherwise. So if it's returning -1, then the call/channel is hungup, and any dialplan instructions after it won't get executed, even though there might be some (or all) pages of the fax sitting in the receive file... Does this make sense to anyone, or am I barking up the wrong tree! My thoughts now are to actually do a hangup at the end of the RxFAX and rely on a 'h' extension to pick it up and carry on with the 2nd half (which is PDFing and emailling the fax), but I'm concerned I'm going to lose the channel variables as it suggests on the wiki, so I'll lose the REMOTESTATIONID string and caller ID... Anyone with any experience of this, or suggestions otherwise?

Thats what I do and have not had a problem, we only do maybe 10-20 faxes a week though. I set my channel variables in a macro and then goto a context receivefax where I enter on s,1,Rx.Fax , on hangup I do the actual mailing and sending of the fax. Before the sending though I make sure the fax actually exists. hth Jeremy ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
