I don't see anything obviously wrong with your configs.
You don't want relaxdtmf. That can cause the problem, not fix it.
In sip.conf [general] put context=INVALID It's easy to configure
Asterisk to accept calls from unauthenticated devices. Putting that
context line in [general] will make sure that, if a device trying to
make a call via your server and does not have a matching sip.conf entry,
the call will fail with a message on the CLI. If you have a typoe in
sip.conf you'll see it pretty fast.
I don't recall if Asterisk listens for inband DTMF in addition to the
dtmfmode= you set. I suspect it does. Make SURE each SIP device is set
to the same dtmfmode as you have for that device in sip.conf. I
recommend using dtmfmode=rfc2833 for all devices, regardless of which
codec they use.
