Hi. I'm working with i4l with asterisk CVS-02/21/03-13:59:12, plus i4l (chan modem i4l *dsp patched* and kernel 2.4.19 patched to disable dtmf). All seems ok (apart some echo issues that seems gone with mec2 aggressive suppressor), but outgoing dtmf doesn't work . or at least I hear the very first part of the dtmf, but then it seems suppressed. here's my modem.conf [interfaces] context=telecom dialtype=tone mode=immediate features=dtmf,noquelch driver=i4l group=1 msn=xxxxxxxxx device => /dev/ttyI0 device => /dev/ttyI1 ingoing calls are ok. any hints?
