The site has a working 824 and just converted to ATT fiber, On incoming calls the DTMF digits are not being recognized by the auto attendant 'at times.'
Tested by sending DTMF with handset at interface - Panasonic is OK.
ATT says there is a 'short haul/long haul option in the Panasonic. I can't find it.

Anyone had this issue?
