I am at a complete loss here… Whenever 1 phone in my network dials certain 800 numbers the DTMF tones don’t play unless I press them extreamlly slow. I have set the phone to both rfc2833 and inband and neither seem to help one way or another. I just upgraded to version 1.8 of asterisk and 2.9 of freepbx and it started happening after that. All other phones in the company work. Thanks in advance for the help.
