RFC3267 doesn't mention any parameter in the SDP to change the bitrate during the call using SIP. It allows the mode-set parameter that tells the encoder the subset of modes/bitrates it can use. It doesn't allow the specification of the bitrate the other end needs to use/switch-to. I came across some 3GPP docs (3GPP TS 26.236: Packet switched conversational multimedia applications; Transport protocols) that suggest using the bandwidth paramter, but that seems to be specific to QoS and I am not sure if this applies to the SIP standard per se. Please let me know if anyone has any insight on this topic.
