If you put a much longer lead between the FAX machine and the SPA3102 you may find it works a lot better. :-\ If you turn up the gains too much you get clipping, but as long as you don't go too far it shouldn't very sensitive.

Is the fax machine connected to the FXS port or do you use the SPA3102 only as a SIP 2 PSTN gateway? If you use the FXS port, please take a look at the gain parameters you can find in the "Miscellaneous" section in the "Regional" page (log in as Administrator then switch to the "advanced" report). Now I've -5 as input gain and -2 as output. I don't know if this could helps you.

Re: [asterisk-users] faxing via linksys SPA3102 half page goes through
Hi Joseph. I've spent some time tuning the SPA3102 FXS line input and output gain and I think that this is an important variable. Let's try to record incoming and outgoing fax tones with asterisk on SIP channel (disabling the fax detection on SPA and sending fax inband) and look at the recorded file with a wave editor (Audacity). I had better results if the maximum level is near half to the full dynamic. Then switch to T38, if you need it. Hope this helps you.

I forgot to note that I'm not faxing through VoIP; fax goes through PSTN but the problem I'm having that only about half a page goes through. -- #Joseph ___ -- 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
