I have a strange problem with an UC520 and 3911 sip phones. I cannot send DTMF from the phones to an external FXO or even to the integrated CUE. I tried multiple configurations and the only partial success I had was with dtmf-relay rtp-nte under voice register pool but I'm getting double digits to the FXO and also to CUE. I also did a debug ccsip events and I noticed that even with dtmf-relay sip-notify under voice register pool I don't get the cc_events generated when pressing a key. Attached is the current config of the box. Thanks in advance for any help.
