Can I use a Node Balancer with Asterisk?

It appears as though our NodeBalancer may not be the best option for load balancing Asterisk. In researching the matter, Kamillo and OpenSIPS seem to be the optimal load balancers for Asterisk. Here are some of the links I found that would helpful:

If you are a NodeBalancer absolutist and would like to try to make it work, HAProxy is a good analog and these high availability patterns may be helpful:
