[App_rpt-users] Question about DMK URL and DTMF

Hello, I recently got my node up and working great, but it was using an old IRLP board for PTT and COS. Today I got a DMK URI USB FOB and replace it, and it works fine. The only problem I have is with certain DTMF commands. For example, I can connect to another node and all works fine. But I am unable to disconnect. Looking at the log files, the DTMF sequence is being recognized ok. Simply the commands are being ignored. If I try to disconnect, it does nothing. But a status *70 works ok. Even trying to connect another node while being connected doesn't work. It works only if I am not connected to anyone. Anybody recognize this symptom? Thanks.
