Hi John,

thanks for the reply and sorry for the late response. Your articles are
quite informative, they made a few bits clearer.
I tried tracing the sequence diagram from your page on the opensips.cfg
file attached in my first post, and I believe all the necessary bits are
there -- I have taken the residential configuration from the config
generator and added an additiona "route[byNumber]" in the flow.

Unless I'm missing something when looking at the config file, I do
believe my config does match the flow you described. However, I have not
looked at the headers in the trace in detail, perhaps that's where my
problem lies?

Thanks,
Thomas
