It's 10.0.1 The phone is a Valley Communications SVC-2 with the following settings: In band or Out of band DTMF tones: Out of band Length of tone on and off time: 100 Out of band DTMF payload type: 102 Under Clusterwide parameters (H.323) we found and set:
H225 DTMF Duration: 100 Audio Bandwidth for Call Counting CAC: 102 ... might be coincidence, and it seems to work.

I don't believe you can edit length of tone or on/off times for RFC2833. To use true inband, you need a universal transcoder. It tries to negotiate a few different methods such as Unsolicited Notify, KPML, and SIP Info (I believe receive but not send on this one). You can't hard set to use a certain out of band DTMF method. It should automatically negotiate. You'll have to check the SIP signaling.
