[OpenSIPS-Users] Record-routing & failover (drouting)

Hi,

thanks very much for your reply. That's also what i thought, first it 
was just a siptrace where opensips sends to the second gw but the invite 
got no Record-route header.

But later on, I was able to reproduce the problem and when adding 
another record_route() the second invite is indeed fixed (contains a 
record-route header)? Maybe there is some other reason for this behavior 
i am not seeing yet?


Best Regards

Max M.
