If Asterisk fails to load the G.729 software codec, the following message should be visible on the CLI and in the log (if logging is enabled):
WARNING[nnnn] loader.c: Module 'codec_g729a.so' could not be loaded.
This line may be preceded by another line detailing the cause of the failure.

WARNING[nnnn]: loader.c:387 load_dynamic_module: Error loading module 'codec_g729a.so': /usr/lib/asterisk/modules/codec_g729a.so: wrong ELF class: ELFCLASSXX

"ELFCLASSXX" may be either ELFCLASS32 or ELFCLASS64, indicating a 32- or 64-bit codec implementation, respectively.
Solution: Install the G.729 codec build matching that of the Asterisk installation.
SELinux may prevent the G.729 codec from loading. This is indicated by the following message:
