now that I have a working IPv6 (SixXS tunnel) connection I would like
to test SC with IPv6 and check if ZRTP/SRTP also works when using IPv6
in particular if I use this together with Phil's original Zfone software.
Is there anybody out there that has some experience with SC IPv6, maybe
how to configure Kamailio/openSER or knows of a public (free?) SIP
service provider (Registrar) that supports IPv6.
