Hoping to get some assistance as BT are moving our landline over to digital voice rather then the old copper lines we are currently on. This is a problem for me as I'm running my own UDM for the network, along with multiple AP's, Vlans ect.
I know for a fact i can't just place my old router into bypass mode, it doesn't have one and is locked down as "home customers" shouldn't be useing third party routers.
Placeing the UDM behind the BT router is an option I suppose but hoping for a better option as Double natting could cause problems with my port forwarding, as well as subjecting me to having to force all traffic though BT's DNS/filters ect. Which was why i moved away in the first palce.
Ideally i don't want to lose the home line either as it's still used by my family so hoping someone here will have a good solution to the issue.
