[Serusers] Proxy Server and DNS

Hi to all I've read SIP Introduction manual and i have a question about the proxy server usage. On the example how the DNS Server return proxy.b.com for SIP address bob(a)b.com? Suppose I have a proxy configured for 2 domain (ex. foo.bar and foo2.bar). The proxy server address is sip.bar; suppose that a user A with sip address userA(a)foo.bar would he likes to call user B with address userB(a)foo2.bar, how have i to configure my ser.cfg????? Any hints on this would be very appreciated.
