Repository: Asterisk


Description
-------

The format compatibility bits need to remain frozen to new codecs.  Otherwise, older channel drivers like chan_iax2 could attempt to negotiate them when they have no support for negotiating any of the format's other potential parameters.  In addition, the chan_iax2 format preference order values sent over the wire have no defined fixed value to represent Opus and VP8.

Testing
-------

Compiles and code inspeciton.

See format.c:format_list_init() and format_pref.c:ast_codec_pref_convert().
The format_list container is used to generate the format_list_array which is then is used by chan_iax2 to determine the format index sent over the wire in IAX_IE_CODEC_PREFS.


Thanks,
