Hi, Few days ago I installed Email2fax application on my Asterisk box. I works but not in 100 %. Sometimes (to be certain quite often) I don't receive the whole fax. My fax machine cuts off transmission in 1/2 or 1/3 of the page. I read about it on a wiki and some user lists and people say that this behaviour could be cause be the Ghostscript and the conversion to the tiff format, but when I sent an email with tiff format as a attachment I got the same result (I receive only half of the page). Other said the this is cause by the 2.4 kernel and I should change it to 2.6, but I'm not sure if they are right. (I must say that I can't change my kernel because of some other applications). I also read that this situation could be caused by the spandsp library. My question is what can I do to have this working in 100 %. Many people say that they don't have such a problem, despite they have similar configuration of Asterisk (same kernel, spandsp). Maybe it is txfax problem? Does anyone have a solution??

Does anyone have a solution??What is the path from your Asterisk box to your fax machine, and what codecs are being used in-between? For example, is it: (?) Asterisk -> TDM -> Fax Machine Or is it Asterisk -> uLaw+IAX -> IAXy -> Fax Machine Or what? Lee.

Hi, The situation looks like this: Email with attached .pdf file ---> Asterisk 1.2 box with qmail, connected to PSTN by ISDN HFC-S card, with a_law codec---> PSTN (ISDN)---> Another Asterisk with the same card and codec ---> fax machine connected to Asterisk by Digium card. Thanks for so fast reply Cheers :) -------------- next part -------------- An HTML attachment was scrubbed...
