Hi,<br><br>I've been struggling with this for a quite long time. Maybe I am not the first asterisk user with this problem, (I try to search on google, but I didn't find anything good). My point is:<br>I try to set up * to work as a fax server. Each incoming fax (from PSTN) should be received on email. Luckily it works. I didn't notice any problem with receiving faxes on email, so rxfax works OK. But when I try send and email which is converted to fax tiff image I got nothing but troubles. I'm able to send a fax, the remote end answers and I'm receiving the fax but suddenly "something" bizarre is happening. The fax is dropping the connection and I get only half (sometimes even less than a half) of the page. Sometimes I'm receiving whole page. 50% of the fax transmissions is OK. I am sure that this is not cause by the conversion to tiff image I check it and I'm sure of it. To me it looks like the txfax application cause some problems.
<br>Can anyone tell me, if the txfax, rxfax and spandsp are reliable (which version)?<br>I also heard, that I should use a Digium cards in Asterisk server to have fax transmission work properly, is that the truth? Why?<br>
Could anyane tell what is the best solution for Asterisk and fax transmission (which version of Asterisk and spandsp, which cards ..) or maybe I have to switch to hylafax?<br><br>My environment looks like this:<br><br>Asterisk1.0.9
with spandsp-0.0.2pre21 and bristuff-0.2.0-RC8p with ISDN HFC-S cards ---> PSTN (ISDN) ---> remote fax<br><br>I also try this with:<br><br>Asterisk1.0.9 with spandsp-0.0.2pre21 and bristuff-0.2.0-RC8p with ISDN HFC-S cards ---> PSTN (ISDN) ---> Another Asterisk ---> remote fax
<br><br>but with the same result.<br><br>Thanks in advance for any hints.<br>Cheers<br><br>Andrew Nowrot<br><br><br><br>
