Subject: Don't allow Answer() to accept a negative argument.
X-Git-Tag: 1.6.2.0-beta1~1474
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=316fb598d2ae9358a111001508e1cfbf3e398877;p=thirdparty%2Fasterisk.git

Don't allow Answer() to accept a negative argument.
Negative argument means an infinite delay and we
don't want that.
