Sonus wrongly expects that, when sending a multi-packet 2833 DTMF event, The sender

This allows a reconstruction of the duration if any of the packets are lost.
final_duration - initial_timestamp = total_samples
However, if the duration value exceeds the space allocated (16 bits), The sender should increment
the timestamp one unit and reset the duration to 0.
Always sending a duration of 0 with a new timestamp should be tolerated but is rarely intentional
and is mistakenly done by many devices.
The issue is that the Sonus expects everyone to do it this way instead of tolerating either way.
Sonus will actually ignore every packet with the same timestamp before concluding if it's DTMF.
This flag will cause each packet to have a new timestamp.

So say you are generating a file that says "please wait for me to complete your call, or generating ringback"
Now you place and outbound call and you are bridging. Well, while you were playing the file, you were generating your own RTP timestamps.
But, now that you have a remote RTP stream, you'd rather send those timestamps as-is in case they will be fed to a remote jitter buffer......
Ok, so this causes the audio to completely fade out despite the fact that we send the mark bit which should give them heads up its happening.

actual timestamps in the frames.
