Alexander Traud commented on ASTERISK-26520:
--------------------------------------------
Have a look at {{opus_generate_sdp_fmtp}}, the variable {{size}}, and the condition {{size == ast_str_strlen(*str)}}.
* What is the value of {{size}}?
* Is {{ast_str_reset}} executed in your case?
I doubt this is ever executed, because the initial {{str}} is never empty but comes with previous SDP data. In the old version, the logic worked. Anyway, please, double-check the values of {{CODEC_OPUS_DEFAULT_FEC}} and {{attr->fec}} as well. I wonder why that case is not matched in your scenario.
