Hello,
Where this endpoint is registered? Can you tell about the call flow?
and is there any particular reason for using H323 for this unit site?
It could be due to sip/h323 interchangeability.
see if you can use SIP for this unit and if that works.
Else you need to debug more on gatekeeper where it is register to see if there is any change in DTMF methods.
Thanks
