--000000000000fca91e05841ca2a6 Content-Type: text/plain; charset="UTF-8" Good day My 10c to add here. Have a look that if the calls that went through successfully have the NSF reported correctly. When using a more reliable T.38 backend connection, the NSF gets overridden by 0xFF (if I recall correctly). I have noticed in my testing that you sometimes get it and in some cases you get a codec line. Just something to think about. On the other hand, seems like you might be having the same issue between Class 1 and 2, just different symptoms. Seems like both fail at the end of sending a page. In class 1 case the receiver discards the fax (possibly because of ECM), and class 2 goes through. You can try class 1 without EMC (this might be degrading your quality though)? I did notice the destination supports JBIG which can be enabled by you by installing libjbig. This reduces the fax page by about 30 - 50% over MMR. Might reduce your time in fax?
