Is there an all-in-one IPv6 to IPv4 proxy for SIP calls?

Do you know a good SIP proxy product that can handle this scenario?

IPv6 SIP clients -------> (Proxy) ----> IPv4 SIP server

  • The IPv4 SIP server is the Registrar as well, so the IPv6 clients should authenticate first.
  • The proxy already has two interfaces, IPv4 and IPv6.

I have already tried Kamailio, I had to manipulate SIP headers (Contact field) and Via field.... I could somehow handle a SIP circuit, but still face issues with RTPproxy. After few weeks, I cannot see the solution is reliable enough. Need to switch over to a tool/product which has been tried before.

Appreciate your comments.

You can handle that using Kamailio/opensips or asterisk/freeswitch.

You should understand that such proxy can be done 2 ways

  1. using NATing. Just NAT your ipv4 range to ipv6 or via versa. If you are using kamailio you also should use rtpproxy.

  2. Working like a multi-ethernet host. You can't just forward traffic, but you can accept channel/create new one and bridge it. Similar to the server with two ethernet interfaces.
