PRACK interworking and RFC3262

Hi community,

 

I have a SBC doing PRACK interworking with an UAC. When the UAC offers a session and the reliable provisional response has an answer, RFC3262 lets the UAC change the offer with the PRACK transaction:

 

If the UAC receives a reliable provisional response with an answer, it MAY generate an additional offer in the PRACK.  If the UAS receives a PRACK with an offer, it MUST place the answer in the 2xx to the PRACK.

 

The point is that, in that case, the RFC forces the UAS to include the answer in the 200OK response to PRACK, which I believe my SBC is not doing. I still couldn't check the sipd logs, but, does this sound familiar, or a limitation of PRACK-interworking?
