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,ColinOn Thu, Jan 5, 2017 at 12:24 PM, anfecora <anfecora@gmail.com> wrote:______________________________Hi guys hope you have a great new year.I would appreciate if anyone can point me in to the right direction .I need to build a proxy to translate from ipv6 to ipv4, but kamailio should not process the registers or invites, only translate from ipv6 to ipv4 and forward all registrations over.is that possible?thanks._________________
