Hi Staffan, My C40 is not behind NAT, still does not work. The 200OK is simply not ACK-ed. The 200OK makes it to the other side (Bria) and is ACK-ed so Bria is sending audio and video. The C40 shows it's accepting Audio and Video in its STATUS screen, but it's not sending anything (because the ACK is not received). After 45 seconds the Tandberg drops the call (the Bye that was 481'ed), this Bye never reaches Bria, who stays in a call.
This could be a new problem then?

Without NAT at least in my basic scenarios the Tandberg E20 seems to work. I tried getting Tandberg to include an option to disable GRUU, but haven't seen it yet. //Staffan On 12 maj 2011, at 13.51, pscheep...@epo.org wrote: I've got a Tandberg C40 codec and as it seems I have issues with GRUU. I don't use NAT or anything. I think http://track.sipfoundry.org/browse/XX-8834 will fully fix the GRUU problem. In the mean time it would be nice if we could get this beast to work properly. Does anybody (Staffan..) know a trick to make it work. Is there an emergency patch for 4.2.1/4.4? Attached the SIP part of the conversation (i left out most of the RTP traffic). The 200OK (frames 8, 13, 18 etc) is not ACK-ed, the C40 keeps trying. In the end (frame 45) the C40 sends a Bye which is answered with a "481 Call/transaction does not exist".
