    Default Codec

    Hi

    Can we get codec information in VoLTE SIP messages. Example AMR-WB 12.65 or AMR-WB 14.25 etc.

    You can find current Codec in the RTP packets.

    Look inside RTP dump for codec in use. If the device has Qualcomm chipset, look inside the ADSP info.

    In the SIP invite you find the negotiated codec(s), you can only find true codec usage in the RTP packets.
