I have a cluster of 6 servers on 220.127.116.110-13. I'd like to use the Click to Call widget, and need to enable and configure the Web Dialer Service. My question is around the placement of the service - or, which of my servers should I enable it on? No.1 is my pub, 2,3, and 4 are my subs followed by 5 and 6 as my TFTP etc.
My guess is that I should enable the service on my subs (2, 3, and 4), because these are the servers that users' phones will be registered to.
I'd appreciate any guidance anyone can offer.
