Subject: chan_local: Skip filtering audio formats on removed streams.
X-Git-Tag: 18.5.0-rc1~38
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8faed04b01be5e5cd4d3044aa3c84555fd492c52;p=thirdparty%2Fasterisk.git

chan_local: Skip filtering audio formats on removed streams.

When a stream topology is provided to chan_local when dialing
it filters the audio formats down. This operation did not skip
streams which were removed (that have no formats) resulting in
calling being aborted.

This change causes such streams to be skipped.
