Yes, this is fine. This is a "pre-loaded" route. They work fine in my 
setup as long as:
- the client uses loose routing (this is the case in your scenario)
- the proxy known that it is responsible for the host/IP in the Route 
header (by default these are the IP addresses openser is listening on. 
For domains they must be specified by alias=....)

e.g. this is not processed in the loose_route block (openser 1.0.0):
INVITE sip:klaus at enum.at SIP/2.0
Via: SIP/2.0/UDP 10.10.0.50:5088;rport;branch=z9hG4bK662862690
Route: <sip:83.136.32.160;lr>
From: <sip:klaus at enum.at>;tag=3909918647
To: <sip:klaus at enum.at>
