[Users] dispatcher relaying instead of dipatching?

[Rick Richardson]

On my test network I have set up a dispatcher server that points to two
proxy servers that hit an external database. 

I have a simple route script on the dispatcher that should be routing
requests to the two proxy servers. 

dispatcher 	.51
caller 		.99
recipient 	.100
proxy1 		.52
proxy2 		.53

I'm making call requests from .99
to .100, with .51 used as the proxy server.
The problem I'm getting, is that the INVITE is being sent directly to
the recipient without passing through the proxys, the dispatcher is
passing the message directly. At least i think that is what is
happening. 
Here is the sip INVITE:
        INVITE sip:rick at 192.168.0.100 SIP/2.0
        Via: SIP/2.0/UDP 192.168.0.99:5060;rport;branch=z9hG4bK837723126
        From: <sip:rick at 192.168.0.51>;tag=679508646
        To: <sip:rick at 192.168.0.100>
        Call-ID: 125992616 at 192.168.0.99
        CSeq: 20 INVITE
        Contact: <sip:rick at 192.168.0.99:5060>
        Max-Forwards: 5
        User-Agent: Linphone-1.0.1/eXosip
        Subject: Phone call
        Expires: 120
        Allow: INVITE, ACK, CANCEL, BYE, OPTIONS, REFER, SUBSCRIBE,
NOTIFY, MESSAGE
        Content-Type: application/sdp
        Content-Length: 352

So it seems to me that the invite request is being sent to .51 and it is
forwarding directly to .100 without dispatching the message to .52
or .53

here is my dispatcher config:
