We are running 10.20.17 and just realized that Zeroconfig is giving our phones the external WAN interface from our PBX.
(It is configured in route mode)
It should be giving the 192.168.. address out as the SIP server but has stopped doing so, it was never an issue before this update.
Its not the end of the world, there is no firewalling etc between them but it is a hop thats not needed.
(Also just saw that a new phone is given the External WAN IP during Zeroconfig as its config source)
THoughts? I checked everywhere, LANs are all configured correctly etc.
