[Serusers] Rewriting Record-Route headers

[Simon Miles]

I had a similar problem with a gateway. In this case it use the number
in the To: header to dial out to PSTN.

In the end I worked with the supplier and they agreed that they ere not
working to the RFC standard and so they have now provided me with new
firmware.


So I guess in your case you need to do the same.

I did not see any problem in the message, so you should probably wait
for reply from the vendor and ask them why exactly did it generate the
reply.
