for example, see load_contacts() and next_contacts() functions of lcr
module.

I'm going to show my ignorance here. I'm reading through the
documentation and old messages floating around the internet and I
really don't get it. The proper use of these functions is eluding me. I
have not been able to get the system to move on and try the second
contact. I can see from the debug that it pulls both records and they
have the right preference and priority but it will not change to the
second one even though the first on is an IP that has nothing on it to
listen on 5060 and can't possibly be seen as a viable destination.
