Claim:
1. A method of operating a user equipment (UE) configured to selectively recover lost media for a real-time communication session, comprising: detecting presence of a lost media packet from another UE participating in the real-time communication session that did not successfully arrive at the UE; evaluating, in response to the detecting, a set of recovery criteria associated with the lost media packet to dynamically select at least one external source from a plurality of external sources from which the lost media packet can potentially be recovered at different predicted reliabilities for recovery of the lost media packet based on the set of recovery criteria, wherein the different predicted reliabilities correspond to different levels of confidence that the plurality of external sources have access to a copy of the lost media packet; and requesting the lost media packet from the selected at least one external source based on the evaluation, wherein the requesting is performed by the UE without advance confirmation that the selected at least one external source has access to the copy of the lost media packet.
