[Asterisk-Users] new version problem

[Altus Snyman]

Good day all
I upgrade my asterisk and the vpb driver to the latest
I used all my previous, working, config files over.
Every thing works well but for 1 thing,playing DTMF when making a 
outbound call
If I call a external number on my phone and another pbx answers and I 
have to press a number it gives this error
"vpb/1-3: chanreads: Not playing DTMF frame on native bridg"
When you listen on the other side there is no sound being made
Please Help
thanks
Altus
