UCM6202 After upgrade to firmaware 1.0.19.21 from 1.0.18.13 fax stop working

Hello
After upgrade to firmaware 1.0.19.21 from 1.0.18.13 fax stop working.
My setup is an isdn line from telco connected to a patton, and patton is sip registered to ucm6202.
I use internal virtual fax (iaxmodem), and setup ucm to auto recognize incoming faxes and send them to virtual fax.
Everything was fine, till firmware upgrade to the latest release as i said.
Is anyone have a solution for this? It is a bug, or mabe i should change some settings?
