Hello,

  Anyone has an experience with the above configuration? All sides are
marked as RFC-2833 and the Sonus recognises most of the DTMF's twice.
The Vega sends both RFC-2833 events and about 60msec of the DTMF tone
(according to Vega's engineers it takes it about 60 msec to detect the DTMF
tones).

According to the RFC this is acceptable. The service provider I am working
with says that it shouldn't be like that. Before I waste time in wars, has
anybody had this issue and knows whether it is a matter of configuration at
the Sonus side?

                                   Thanks! __Yehavi:
