Subject: func_cdr: Allow empty value for CDR dialplan function.
X-Git-Tag: 13.16.0-rc1~14^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c3ed63cb2cc89e89bec15d29f1d332aa7ece5bc0;p=thirdparty%2Fasterisk.git

func_cdr: Allow empty value for CDR dialplan function.

A regression was introduced in 12 where passing an empty value
to the CDR dialplan function was not longer allowed. This
change returns to the behavior of 11 where it is permitted.
