1. A method of wireless communication performed by an answerer, comprising:
receiving, from an offeror, an offer including a first plurality of quality of service (QOS) parameters for a multimedia session to be established between the offeror and the answerer, the first plurality of QoS parameters including a first latency parameter indicating a first desirable maximum end-to-end packet latency for the multimedia session in milliseconds, the first plurality of QoS parameters received in a first session description protocol (SDP) message;
determining that the first desirable maximum end-to-end packet latency is higher than a second desirable maximum end-to-end packet latency for the multimedia session; and
sending, to the offeror, an answer including a second plurality of QoS parameters for the multimedia session, the second plurality of QoS parameters including a second latency parameter indicating the second desirable maximum end-to-end packet latency in milliseconds, the second plurality of QoS parameters sent in a second SDP message,
wherein (1) the offeror is a user equipment (UE) that originates the offer and the answerer is a non-UE network node that originates the answer, or (2) the offeror is the non-UE network node that originates the offer and the answerer is the UE that originates the answer, and
wherein the multimedia session comprises a FLUS session, a multimedia telephony service for internet protocol (IP) multimedia subsystem (IMS) (MTSI) session, an extended reality session, a telepresence session, or a split rendering session.
