Ouch!! Not IPv4/IPv6 translation of SDP addresses?
Thanks Klaus and Jan for your answers. Well, I thought on a device with 2 network cards because I want to divide IPv6 and IPv4 networks.
Do you know whether SER is going to be able to translate SDP addresses in the near future?
I have another question. Is the SIP IPv4 server a mandatory device in this scenario? I mean, I think I can use the SIP IPv6 server and the IPv6/IPv4 translator and nothing else. In this way, IPv4 devices would have the translator as SIP Proxy, and the translator would redirect thier request to the IPv6 SIP server. So there would be one domain and one registrar.
What do you think about this? Is this possible?
Thank you very much

As mentioned by Klaus, one network device with both IPv4 and IPv6 addresses will do the job. You then need to configure ser to listen on both of them and make sure that record-routing is enabled.
SER can translate SIP signalling, what it can not done yet is IPv4- IPv6translation of SDP addresses.

Hello
After installing and running over last month SER, we are going
to the
next step. Our final goal is to deploy a SIP network which
allows SIP
clients Voice Call, Videoconference (RTP), Instant Message and Presence. And we want to use IPv6 and IPv4 networks.
I wonder several questions about this:
I'll use a SER server for IPv4 network and another for IPv6
network,
but how I connect them? I think that I need a device with two
network
cards connected each one to IPv4 or IPv6. Which software has
to run
this device to act as a SIP Protocol Gateway? Can SER do this?
Do you think that with the two proxy SER servers and the SIP
Protocol
Gateway would be enough or that I need another device to develope this?
Thank you very much for your time and responses

Not yet, though Maxim's RTP proxy supports the translation.

I hope so (It has been on my todo list for a while, but with low priority).
I have another question. Is the SIP IPv4 server a mandatory device in this scenario? I mean, I think I can use the SIP IPv6 server and the IPv6/IPv4 translator and nothing else.

This will probably not work, the problem is that in this scenario you would have to translate REGISTER contacts as well. That means you would have to encode the original contact into an IPv6 one and then decode it when a request comes for the UA. Mangler can do it, but it probably doesn't support IPv6.
