<div>Hi,</div>
<div> </div>
<div>It sounds like Asterisk should handle T.38 fax (at least at very light load). However, I am having troubles faxing through a Linksys PAP2 NA. It doesn't seem to get through at all. Everything else (voice calls) works just fine. I am using Asterisk Business Edition (
ABE-A.1). I have faxdetect=both in zapata.conf, and I wonder if there's anything else I'm missing. I know I won't get 100% with fax over IP, but the success rate for fax on my Asterisk box is just way too low (about 5%, I would say).
</div>
<div> </div>
<div>Can you please tell me what ATA you are using? Could it be that the PAP2 doesn't support fax?</div>
<div> </div>
<div>Please advice.</div>
<div>Thank you.</div>
