    abstract =  {During the migration from IPv4 to IPv6, it is anticipated that an IPv6 path might be broken for a variety of reasons, causing endpoints to not receive RTP data. Connectivity checks would detect and avoid the user noticing such a problem, but there is industry reluctance to implement connectivity checks. This document describes a mechanism allowing dual-stack SIP endpoints to attempt communications over IPv6 and fall back to IPv4 if the IPv6 path is not working. The mechanism does not require connectivity checks.},
