Subject: chan_dahdi: Fix analog dialtone detection.
X-Git-Tag: 13.0.0-beta1~275
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=4c252096ef90d79a0da69daedaf09898b47a675b;p=thirdparty%2Fasterisk.git

chan_dahdi: Fix analog dialtone detection.

* Check if waitingfordt (waitfordialtone) is enabled in dahdi_read() to
allow the DSP to operate early enough to detect dialtone.

* Made use the correct variable in my_check_waitingfordt().
