[OpenSIPS-Users] A Record-Route header field exists in 200 OK from openser-1.3.4-12.fc13.i686 SIPv6 Registrar Server

[Bogdan-Andrei Iancu]

Hi,

the RR header is mirrored in 200 OK as it is present in the request - 
that is how SIP works.

Better check how is responsible for adding the RR in REGISTER request. 
Anyhow, that RR in 200 OK is more or less harmless.

Regards,
Bogdan
