I have Axon installed on a server that has multiple public IP's assigned to it. I've configured Axon to use one of them (not the first IP on the NIC), and Axon ignores this and takes the first two IP's on the NIC as Private and Public, respectively. Oddly, to connect to Axon from my HT503, it works for the IP that Axon has picked for its Private IP, not the Public one. Neither of these IP's are what I set in Static IP. UPNP and STUN are both turned off.
Additionally, I have Axon's Internal Voicemail enabled, and it registers extensions 500 and 501 at 127.0.0.1 instead of using any public IP. When I call another extension from my HT503 and it tries to go to voicemail, the call disconnects in 2 seconds and nothing is recorded.
Static IP I set was 65.111.244.13 which is the 6th or 7th IP on the NIC
IP 65.111.244.8 is the first IP on the NIC
IP 65.111.244.6 is the second IP on the NIC
