1) Good job posting your Version with Build.
2) Please consider including your installer with full version in future posts.
3) No image attached. lol
4) Instead of looking at the matter from a "look at that forest!" perspective, try checking a call or two (or a dozen?) to see if they should have been answered. If you find any that should have been answered, but were not, check the log during the time of that call and see if you can find out what happened. There may be an error in the asterisk log that tells you what happened.
5) On the other hand, if you completed all your lists and reset them and dialed the numbers again, and you dialed previous "NA" calls, those cancel/NA calls were NA again and were likely a major percentage of the calls you could dial again. Previously all the leads were "NEW" and you removed a lot of them by talking to people, now you have a smaller selection and that would make the NA calls a larger percentage of the remaining calls. Happens a lot.
Happy Hunting!
