Hi,
interesting to know, i wasn't aware that Cisco IOS support dual-stack
VoIP; i wonder how they've implemented it.
The shortcut works for single-stack/RFC6157 devices only, maybe i
should add this to the docs.

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?
