Hello Olle,

> A new URI scheme doesn't make any sense, since a SIP uri can be resolved to many different hosts using NAPTR/SRV records.

This only helps with the SIP communication -- but it gives no certainty
about RTP.  Interoperability between IPv4-only and IPv6-only relating to
media can only be found when trying to setup a call, right?

> A phone that is dual stack can register with two contacts, one for each address family. ICE will take care of media handling.

There is no formal relation between the IP version used for SIP and used
for RTP.  This is what I am proposing to solve with sip6:


Thanks,
 -Rick
