I looked at some v34 logs.

In one case hasv34trouble was flagged into info/<faxno>:

Then I have another case where in the last month, I got 9 times the same error on 13 jobs, this was not flagged as trouble in info/<faxno>. Feb 02 17:06:43.03: [ 4777]: --> [9:+F34:13,1] Feb 02 17:06:43.03: [ 4777]: V.8 handshaking succeeded, V.34-Fax (SuperG3) capab ility enabled.

Feb 02 17:06:55.62: [ 4777]: SEND end page Feb 02 17:06:55.62: [ 4777]: <-- data [3]

However, I have another receiver where the same error (Failed to properly
open control V.34 channel) happened just 1 time in 55 tries (54 tries OK).


So, this error is quite complicated to handle.


Yes, determining "hasV34trouble" automatically is difficult.

Is this a case where we should edit by hand info/<faxno> and force 34trouble
case by case?


Probably, yes.

Do you have experience that Brother are a bit troublesome?


Yes, Brother fax machines tend to be the most annoying. Even the non-V.34 ones are a pain. Even the non-ECM ones are a pain.
