Actually-scratch that. Not sure why this changed, but I restarted asterisk, and now INFO DTMF is playing into the bridge, so that doesn’t seem to change anything from a mixing standpoint. I did verify that the trunk dtmf mode is set to info.
So, back to the original question-is there a way in ARI to intercept and block DTMF from a conference while still getting the events? I’d like to conditionally relay to specific channels within a bridge.
