Hi Daniel,
Thanks. I can see now what I have done. I'm using the same branch route for
initial requests and also for loose routed requests.
It either needs a test like the one you suggest or maybe use a different branch
route for loose routed requests.

Subject: Re: [SR-Users] uac_replace_from() and multiple branches
Hello,
the reason for writing the error message seems to be that you execute the
uac_replace_from() for requests within dialog (e.g., re-INVITE, BYE). In
auto-restore mode it has to be done only for the initial request (first INVITE
of the call), then the module does automatically the changes for requests
within the dialog and the responses.
You should add a condition like:
if(!has_totag()) { ... }
Cheers,
Daniel
