Description:	*Note:* this issue applies only to work that is being done for the new media format architecture branch (team/group/media_formats-reviewed-trunk). The {{IAX2}} channel driver is a bit odd, in that it must treat formats using the historical bit field representation. As such, a compatibility API ({{format_compatibility.h}}) has been provided to map formats/codecs to their bitfield equivalent. The code compiles. The module does not load due to a linker error: {code} *CLI> module load chan_iax2.so Unable to load module chan_iax2.so Command 'module load chan_iax2.so' failed. *CLI> [Jun 26 19:41:39] WARNING[19300]: loader.c:561 load_dynamic_module: Error loading module 'chan_iax2.so': /usr/lib/asterisk/modules/chan_iax2.so: undefined symbol: ast_codec_pref_convert {code} We need to make {{chan_iax2}} work. It needs to maintain its functionality using the format compatibility API. Preferably, it should not crash, leak memory, or otherwise mess up our lovely new API :-)
