[ Summary | Information ]


This article describes the changes in the new SX2 Release-Driver v8.0.0.5.


The new driver v8.0.0.5 fixes an issue regarding DTMF tone generation.

With previous driver versions it can happen that DTMF tones from the SwyxWare into the ISDN network or to a Sub-PBX will be transferred too loud which might lead to a faulty tone detection on the other side.
