<p> What is the best way to debug DTMF on a PJSIP trunk? I have
cycled through all available options (<span title="latin1_swedish_ci">'rfc4733','inband','info','auto','auto_info')
but my IVR does not recognize any options from the remote end.
I have also tried changing codecs from g729 to alaw or ulaw with
the same result. Outgoing calls do not seem to have this
problem, just incoming. This is with Asterisk 13.29.2 but the
problem started with 13.21 before I decided to upgrade to the
latest 13.x version. Any pointers?<br>
