Description (partial)

Symptom:
A TelePresence Server may poorly detect badly-formed DTMF digits from some RFC2833 voice gateways and triple count the tones.

Conditions:
Only present in the 1.22 and 1.42 EFT releases of TS 4.1. This requires the sending DTMF device to have set the marker bit for each packet in a given DTMF tone, which is technically incorrect behaviour on the part of the sending device.
