Torrey Searle commented on ASTERISK-27381:
------------------------------------------
The crash is a result of failure to initialise the codec. The codec fails to initialize because of no value set for application.
Application is not getting set (not even to a default) because codec_opus_config_attr_cfg somewhere between line 62 and 69 sets cfg to null
