It seems like every once in a while we get an asterisk version where DMTF is broken.
We have recently upgraded to 220.127.116.11 using rpms via yum
Since upgrading we cannot use DTMF while dialling out on any of our SIP trunks, we have tried rfc2833, info and auto.
Nothing seems to work, and DTMF can no longer be used.
Can someone help? Its getting beyond a joke that every once in a while we get a version where DTMF stops working altogether!
