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.<BR>
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).<BR>
<BR>
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?<BR>
<BR>
Thanks! __Yehavi:<BR>
