I have verto working and can make calls, but I can’t seem to get DTMF working. I am using fusionpbx and need to enter a conference room pin number however once I enter the conference extension number and get asked to enter the pin it just always says “invalid pin”. 

Looking at the logs, I don’t see any DTMF getting passed back to freeswitch. Is there a config option I can do to enable the keypad?

Thanks
