> This patch cleans up asterisk's SDP parsing algorithm, resolving a few bugs including #14994. It does the parsing line by line, making a distinction between session-level and media-specific parameters. It also optimizes the parsing adding functions for audio/video/image specific scanning.
> I added debug information for a better understanding on how the parsing is actually done (shows each SDP line parsed with OK or UNSUPPORTED).
