I really, really prefer the faxing in 1.6. It's so nice to configure compared to 1.4. I'll leave it to the ChangeLog and anybody else who wants to chime in on actual differences. > I was using PSTN. Great. Because trying to track down voip faxing problems is much worse. > hardware provided determine from examining server logs.

When I was troubleshooting things, I started recording 100% of faxes, and then just blowing them away after a few days with a cron. If I wanted to go back and troubleshoot a particular customer, I could filter by their calls and listen to what was going on. It was amazing how lousy some of the faxes were and it was obviously the customer's fault. I never would have been able to tell that without listening to the audio recordings of the fax transmission. In other cases, it was robodialers wardialing the world, and they weren't even sending a fax. I discovered I had to be VERY careful how I calculated error rate. If you count by absolute successes and failures, the early failure rate looked awful. This was directly correlated to the customers with crap connections retrying the same faxes that were never going to succeed over and over again. When I instead sorted successes and failures by sending phone number, I got very high 90s success rate. This of course, also requires that you're keeping logging in a way that makes this kind of diagnosis possible. Hopefully you have good records. _______________________________________________ -- 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
