Subject: chan_pjsip: Only set default audio stream on hold.
X-Git-Tag: 18.13.0-rc1~18
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6e8e5e49afb8e089cd2a2e37f9881639a09574d9;p=thirdparty%2Fasterisk.git

chan_pjsip: Only set default audio stream on hold.

When a PJSIP channel is set on hold or off hold, all streams were set
on/off hold. This is not the desired behaviour and caused issues
when there were multiple streams in the topology.

Now, only the default audio stream is set on/off hold when a hold is
indicated.
