hi, i have 2 setups running FS with the exact same profile and dialplan, one running on windows and the other on a raspberry pi, both receive calls from registered clients and forward to a remote gateway, the problem is when client sends dtmf, the windows FS forwards to gateway without issues but on the rpi most of the times fs isnt able to detect dtmf or at times detects but doesnt or partially sends to gateway. i have been banging my head with this from a few days but no idea whats going wrong, the client sending to rpi FS i even made him send call to gateway directly and then that works so this rules out client issue, no idea whats wrong with FS, both are on the latest build im using g711u throughout -- Regards, Bipin ------------------------------------------------------------------------
