Hi HP,

I recommend you to check modern mr9.5 LTS.
there were some SRTP fixes the last year for mr9.x scope.
Most of them have been backported to all supported LTS,
but for sure all of them are part of the latest mr9.5 LTS.
I hope community will assist you further with faxes on CE.

Just in case PRO system has built-in FAX solution
and Sipwise Ops team will help you there with pleasure!
Crazy things like FAX transcoding is also possible on NGCP,
you can find more details here:

Enjoy Sipwise NGCP!
