[Kamailio-Users] Looking for a highly available / load balanced setup

[Zahid Mehmood]

Thanks for your reply.

May I trouble you and others on the list to share the deciding factors  
(pros & cons)  for choosing the option that you did.

I'm trying to get a better understanding circumstances in which you  
may choose one over the other.

What, if any, special considerations are there for the presence part?


Thanks.
