Subject: rtp_engine: Allow Media Formats with add_static_payload(-1) on egress again.
X-Git-Tag: 15.5.0-rc1~63^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a36d45bdcb27d3c03005567b2885b7ec471aefa5;p=thirdparty%2Fasterisk.git

rtp_engine: Allow Media Formats with add_static_payload(-1) on egress again.

This issue affected only installations with rtp_use_dynamic=yes in asterisk.conf
which is the default since Asterisk 15. Codec 2 and SiLK were built-in examples
of media formats which were affected.
