Hello, I found that the frame length definition for AMR-WB bitrate 12.45 is incorrect. This bitrate has a frame length of 285 bits, which corresponds to 36 bytes. However, pjmedia_codec_amrwb_framelen[3] is set to 37. This makes the buffer availability check fail in pjmeda_codec_amr_pack() if the caller does not provide an extra byte in the payload. Regards Zoltan

Hi Zoltan, You are right. But unfortunately, there doesn't seem to be an easy way to fix it without affecting backward compatibility. So what currently happens when the framelen is set to 37. Does the client fail with assertion or only one-way audio?
