[Asterisk-Users] RxFax - Fast carrier training failed

[Steve Underwood]

Hi Mike,

To get something like:

Coarse carrier frequency 1832.96 (4)
Training error 927.702492
Training failed (convergence failed)

something is horribly wrong. The carrier should be 1700Hz, not 1832.96Hz :-)

Do you have a codec mismatch, or are you using a codec other than u-law 
or A-law? Sometimes the slow control messages will get through the wrong 
modem, but the fast modem for the images never will.

Regards,
Steve
