We are currently planning a PureCloud rollout. In an active-active configuration with multiple edge devices, using the standard DHCP approach to provision phones, I am trying to understand how the phone selects which edge is primary and which is secondary.
- Does it treat whichever one the DNS lookup returns when the DHCP process is occuring as the primary edge? If so, to achieve an even distribution of phones to edges, does the DNS need to be doing a round robin when returning the IP of the edge?
- If it's not based on this, then how does it work?
