In the IETF Sipcore working group, we're starting work on "Happy Eyeballs for SIP", getting systems that use both IPv4 and IPv6 to work well, even in situations where connectivity in IPv6 is not assured. We expect that the changes to the SIP specifications will be small or none, but that there are a number of best practices that can be recommended to improve user experience.
I'm asking here to find out if anyone has implementation experience in this area that they'd be willing to share. Dale _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
