[SR-Users] Reinite breaks the call

Hello,
you have to provide the sip traffic on both sides to be able to
troubleshoot. The re-INVITE has to come in with the R-URI being the
Contact address sent back to caller via 200ok in order to match the
topos session. The re-INVITE sent out indicates no topos processing was
done, because the Via stack has many addresses, it should be only 1 Via.
Cheers,
Daniel
