You can do this several different ways:

1. Set up a DNS SRV record for your domainname.
_sip._udp.example.com	-> 	0 0 5065 proxy.example.com

2. set an outbound proxy in the profile
Profile profile;
Uri ob;
ob.host() = "proxy.example.com";
ob.port() = 5065;
profile.setOutboundProxy(ob);

3. use a preloaded route
SipMessage& reg = dum.makeRegister(target);
reg.header(h_Routes).push_front(NameAddr(ob));
