Hi, >Martin¹s statement says SHOULD here and does not mandate. ICE keepalives could also be used to keep the NAT state There needs to be a good justification for a SHOULD, and consent was never intended for NAT keep-alives. Also keep in mind that, with the "virtual connection" concept, there might be a big number of ICE connections - some of which you may never use. Why send consent on those, if there is no media?
