In some embodiments, the P-CSCF serving a PLMN passes through the ANBR attribute in the SDP when the P-CSCF recognizes that the PLMN supports ANBR functionality. In some embodiments, the UE can include ANBR attribute in the SDP offer and answers when the P-CSCF indicates its support for the ANBR attribute in the SDP.
