Multi WAN, unique public IP

@chpalmer said in Multi WAN, unique public IP:
If you somehow cause the phones to see a disconnect from their ethernet connection when a WAN changes then they should re-register with the PBX.
This should be achieved by checking System > Advanced > Miscellaneous > State Killing on Gateway Failure in pfSense. So on failover it drops the connection and the phones need to reconnect again.
However, this will also drop a call, presumably. -
That is just the state.. The interface light on the phone needs to go out.

I see. Didn't know that.
Reconnecting to the PBX is not sufficient for renewing their public IP? -

There actually is not any continuous traffic to the SIP server.. Unless you are making and receiving phone calls (of which the RTP does not actually have to touch the same SIP server) the only time traffic goes back and forth is when the phone attempts to re-register. The SIP server may never know that your phone is offline until it stops getting reg data.
Look at the expiration data below.. Until that time comes the phone wont say a peep to the SIP server unless you are making a call.

So the pones also don't notice when your WAN connection goes down, I guess?
I'm not familiar with SIP. -

I'm not familiar with SIP.Nope. Not until they try to make a call at least..
SIP was never originally designed for the type of use it sees today and has had allot of changes to allow things like the addition to work with NAT.. Vonage changed all that.

Is it possible to "go out" with a third public ip regardless of the used connection, so that it is always the same?
It sounds like you are looking for an SD-WAN service. Basically the IP is from them, and they adjust routing between/among ISPs. I looked into it briefly a while back. Not sure how it interacts with pfSense since they seem to provide a router, then the ISP routers connect to that. Perhaps one can bridge to pfSense.

I do not understand of voip and pbx, and I have not configured the phones, I only did some tests: the technician who installed it says that with other firewalls (watchguard) they have no problems with failover rule, .. I try to report your indications ...many thanks!
