[Serusers] Call btn two SIP Servers

The prob is pretty basic. I have installed 2 SERs and have a set of
 users registered to either of the proxies. How can i place a call from
 user1 at SER1 to user2 @ SER2?

This is what i've done

1. In my "domain" table (i.e. MySQL) in both SER's I have  added
domain entries.

2. Then into" trusted" tables of either proxies , i've added the value
of the other proxy

3. Then made the entries in the ser.cfg. But when i restart ser i get
this as the error
[root at localhost sbin]# service ser restart
Stopping ser:                                              [  OK  ]
Starting ser: ERROR: bad config file (3 errors)
                                                           [FAILED]


My ser.cfg of one of the Proxies is as follows... can anyone help??? pls?
