Hi Bogdan,
Here is a full trace, breakdown is like this
.2 INVITES to .164
.164 INVITES TO .168
.168 sends a 302 to .164
.164 sends .2 a 503 followed by a 302
.2 should never know about the 302 at all, but it's still getting back
to the originating proxy.
We are not using get_redirects() to do anything with the 302 - from some
Googling and such it appears that might be needed, just not sure how it
would be used.
Thanks for looking at this.
