Re: [sr-dev] git:3.3: New Option: "x" for automatic bridging between IPv4 and IPv6.

We did agree, that SDP would probably never contain both IPv4 or IPv6 addresses. RFC 6157 (https://tools.ietf.org/html/rfc6157, "IPv6 Transition in the Session Initiation Protocol (SIP)") also recommends using ICE for SIP-IPv4/IPv6 dual-stack.

ok, i need to read it.

If we follow this RFC and typical UA's, we will always have "either/or" rather than "and". However, i've never seen any dual-stack SIP-Endpoints so far.

at least cisco ios gateways support dual stack:

protocol mode ipv4 | ipv6 | dual-stack [preference {ipv4 | ipv6}]}

so what should sip proxy do when $rd is domain name?
