In this case, I am suggesting that the systems do not route requests directly to each other but that they go through a back to back user agent to re-write the request. If I go through a Back to Back user agent, I can always have these B2BuAs do the necessary transformations. Mechanistically it would work as follows: When sipxbridge sees a request bound from system A to system B it locate the " ITSP record " for system B based on the request URI and make the necessary transformations to the request to send it to system B. It would attach a Route header to send the request to system B. What would be the issue with that? Ranga > > > -- M.
