Subject: Fix a regression where direct media was not permitted for calls using SIP INFO DTMF.
X-Git-Tag: 10.10.0-rc1~51
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7af34e67ad55defd5d64da19e354ec58fed046c4;p=thirdparty%2Fasterisk.git

Fix a regression where direct media was not permitted for calls using SIP INFO DTMF.

A change was committed to fix direct media ACL support. This change wrongly assumed that
only a single channel technology structure exists for chan_sip. This is in fact false as
a second exists for calls using SIP INFO DTMF. The code which performs direct media ACL
checking now checks for both the non-INFO DTMF and INFO DTMF channel technology structures.
