The specificity of almost all of these scenarios lies in the user agents that are the endpoints of the call, and not the proxy.

So, while they might be useful end-to-end tests of your entire service delivery platform, they are broken down according to a taxonomy that differs from the proxy's state machine and functional orientation.

I do take your point.

So since I correctly handle initial requests and the replies, and can handle in-dialog requests and replies, and deal with those hop-by-hop requests, I can just relax and be happy?

As you say, my different end-user scenarios boil down to the same "elements", but in practice my tests did find a problem with the way my Enswitch proxy was handling loose-routed NOTIFYs.

Users are very good at finding odd corner-cases, so it seems helpful to consider in advance flows that exercise unusual paths through the proxy config.

Regards,

Steve
