SCN with Públic IP - 3 Sites 3

[AndersonTelecom]

Hello guys,
I have 3 units of IPO 500 V2 8.0, installed in different locations with IP Public (200.28.453.XXX, 200.28.113.XXX and 200.28.452.XXX).
Are not DHCP. The IPs are fixed
I need to know if an SCN network work through these IP with open internet.

Thank you for your attention

With SIP trunks work?

You would have some documentation that talks about this?

While IPO WILL work with public IP, it is very dangerous to do so. If it were me, I'd create a VPN between the sites. I'm not sure how SIP trunks would fit in, as they don't accomplish the same as SCN. However, if you want SIP, I'd still have IPO behind NAT. Cheap insurance.

It would be easy to setup a VPN between your 3 sites. Do that.

If you HAD to run it over the public IPs you would need to have a firewall that could lock down communication to each IPO to only the other IPOs it should be talking to. Yes it will work. No it is not good practice.
