Slyon already talked to me about the second channel fsogsmd has to use to get the unsolicited response when a call ends. I told him listening on two channels should be possible with implementing something like a combined-transport. I have this in my list for implementation but it will take some days to get it implemented and tested on the device.

About the unexpected behaviour for the send dtmf command, please don't do this in the fsogsmd core layer but in the plugin until wie verified it's something we have to change for all modem types.
