It could usually be resolved by changing the port settings to give a longer or shorter DTMF tone duration. I've also seen this with defective analog phones, but that wouldn't explain it working after a reset. \| VBC Salinas \| Valley Baptist Church, Salinas - worship and prayer for Salinas California

On a digital set they are not used because the data stream between the phone and the system tells the processor what is being pressed. When they don't work the system is "deaf" to touchtones. On the SV8100 there is a program for these resources called "DTMF and dial tone circuit setup". They can be set for use by analog stations, trunks, or both. Then norm is to change the setting to both. Now I have no clue about the SV8300 and how it allocates resources but you may want to search the manual and see if "DTMF and dial tone circuit setup" is in there.
