Subject: app_dial: Fix DTMF not relayed to caller on unanswered calls.
X-Git-Tag: 21.0.0-pre1~128
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=95a41d231ff4ca199810a375d2b2781bf981a1d3;p=thirdparty%2Fasterisk.git

app_dial: Fix DTMF not relayed to caller on unanswered calls.

DTMF frames are not handled in app_dial when sent towards the
caller. This means that if DTMF is sent to the calling party
and the call has not yet been answered, the DTMF is not audible.
This is now fixed by relaying DTMF frames if only a single
destination is being dialed.
