Hello
Again, thank you very much. But with your answers, newer questions appear.
Well, If I have understood all right, with RTP proxy I can establish a communication between v4 and v6 clients, so I can 'jump' the problem of not SDP translations. Is this OK?
And I would like to ask you about the simplest scenario I can imagine to interconnect IPv4 and IPv6.
A box (probably IBM with Linux or Sun/Solaris 8) with two cards, one IPv6 and other one IPv4. This box acts as a Proxy Server and Registrar. But it can acts as IPv6/IPv4 translator (I just have to configure ser.cfg to listen on both cards and enable Record-route, haven't I?). And finally this box can acts as RTP Proxy. So, all the features on the same machine. What do you think about this scenario?
Does RTP Proxy work on Solaris 8?
Thank you very much

Put into the ser proxy a second NIC and configure it as IPv6 only. enable Record-route and ser will do the v4-v6 translation. For establishing an RTP-stream between v4 and v6 clients you can use rtpproxy. Take a look of the recent rtpproxy thread in the mailing list,there are some explanations what is already supported by rtpproxy and what has to be done.

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

rtp proxy can tranlate the media streams, but there must be something which will put IPv4/IPv6 address into SDP respectively and force RTP proxy when necessary (when IPv4-IPv6 conversion is needed). That's the missing piece.
And I would like to ask you about the simplest scenario I can imagine to interconnect IPv4 and IPv6.
SER sitting on the boundary and having access to both networks.
A box (probably IBM with Linux or Sun/Solaris 8) with two cards, one IPv6 and other one IPv4. This box acts as a Proxy Server and Registrar. But it can acts as IPv6/IPv4 translator (I just have to configure ser.cfg to listen on both cards and enable Record-route, haven't I?). And finally this box can acts as RTP Proxy. So, all the features on the same machine. What do you think about this scenario?
I would recommend linux. Also note that all the media traffic will go through your box when RTP proxy is used.
Does RTP Proxy work on Solaris 8?
I have never tried, but somebody reported it was working if my memory serves.
