[SR-Users] using kamailio to forward ipv6 to ipv4

[Colin Morelli]

Can't answer whether or not it's possible as I haven't tried it - but,

Consider how this will impact the negotiation between clients and servers.
If your B2BUA thinks calls are coming in from IPV4 (instead of IPV6), then
it may not offer IPV6 in the invite. Similarly, if the client thinks it's
connecting to your SIP infrastructure via V6, then it'll likely offer V6 in
the invite which your B2BUA can't accept. ICE can probably help here, by
offering both V4 and V6 candidates, but that's going to depend on your
client/server setups. Unless you want Kamailio to proxy media s well, in
which case you may be able to escape this, but by adding complexity you
Kamailio.

If at all possible, I'd try to preserve the source protocol through to the
end. If this is something you already thought of though, great! Would be
good to hear what you come up with here.

Best,
Colin
