The customers fax machines will connect to their PBX that has a PRI to an IAD/TA. We have the IAD/TA configured for SIP signaling to an Acme SBC selecting T.38 as the preferred codec with fallback to g.711 pass-through. We can force a slower speed, disable error correction, disabled VAD but in the end still have very inconsistent results. From a network perspective the QoS is matching and queuing correctly, the circuits are clean and the IP SLA gives us no reason to believe they are having any network drops or jitter.<br><br>I was wondering if others who have experience with faxing over IP could share what they have learned works best or anything else that may be helpful.<br><br>Any help is greatly appreciated.<br><br>Thanks,<br><br>Jeff<br><br><o:p></o:p></p><pre><o:p> </o:p></pre><pre><o:p> </o:p></pre><pre>_______________________________________________<o:p></o:p></pre><pre>VoiceOps mailing list<o:p></o:p></pre><pre><a href="mailto:VoiceOps@voiceops.org">VoiceOps@voiceops.org</a><o:p></o:p></pre><pre><a href="https://puck.nether.net/mailman/listinfo/voiceops">https://puck.nether.net/mailman/listinfo/voiceops</a><o:p></o:p></pre><p class=MsoNormal><br><br><o:p></o:p></p><pre>-- <o:p></o:p></pre><pre>Lee Riemer<o:p></o:p></pre><pre>Director of Technical Operations<o:p></o:p></pre><pre>Bestline Communications, L.P.<o:p></o:p></pre><pre>Voice: 1+512.328.9095<o:p></o:p></pre><pre>Fax: 1+512.328.0038<o:p></o:p></pre></div></body></html>
