[Users] Problem with dialog module

Hi Leonid,
you should not do RR for the sequential request. According to RFC3261,
the routing set is established by the initial request (formed by RR set
+ contact) and it does not change across the dialog lifetime.
The clients should ignore any RR from the sequential requests (like
re-INVITEs) and to keep using the RR set form the original INVITE.
regards,
bogdan
