-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'm not sure whether I'm right here or not. But maybe someone has faced same problem: Scenario A: I'm using Sangoma A104d and FreeSWITCH Version 1.0.head (17097:17188M). I enabled hardware based detection of fax and dtmf. Further hardware based HEC is enabled I'm not able to reveive a FAX (analog) via PSTN, while sending works and internal (SIP) works as well. So there is no problem with the ATAs I use nor with the network (which routes the RTP along 80 kilometers one way). Scenario B: I'm able to receive FAX from pstn with same setup, but have hardware based HEC disabled. So in this case everything works fine. I thought sangoma's hardware based Fax detection feature should have disabled HEC when a Fax is detected, but it doesn't seems so. So my current thoughts are about the question whether FS is able to disable hardware HEC via mod_openzap and wanpipe driver for the corresponding A104d channel, when FS knows that the target is a FAX device ... -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) iD8DBQFL6tu84tZeNddg3dwRAur3AJ4rOw5ocXm+aGG7spLYtA4yx23eHACfcUPF K+VHsbNiCR0XQeztzeI4iTY= =ihsg -----END PGP SIGNATURE-----
