Here is the quick structure: There is a headquarter(300users) There are 20 branches (200 each)
I was given a task to replace skype with something else. I have installed OpenFire server with AD authentication, running at HQ for TEXT. Now I need to add audio/video calls to existing environment. All clients support SIP.
What I want to do is install Asteriks on the same server with OpenFire and make them work together.
My question is, will it put much load on the network, taking into account that there are about 4300 users?
Are there any solutions for load balancing?
