Yes, we are aware that the VPM currently breaks FAX tone detection. For 
a temporary workaround, you can add 'vpmdtmfsupport=0' to the module 
parameters for wct4xxp and it will stop this behavior without disabling 
the echo canceler.

We are working on finding a solution for this issue, and once the driver 
is updated with a fix there will be a notice made to the lists.
