Looking at BT broadband with the Hybrid Connect 4G backup. Question relates to what happens to a static IP address when the landline drops & the 4G connection kicks in - does the static IP address get assigned to the 4G connection to allow services that rely on it to continue working (this is for an IP phone installation).
The incoming calls rely on the static IP address of our broadband connection to find our office - but (I am assuming) when the landline drops and the connection is taken up by the 4G connection, a different IP address will come into force and the incoming calls won't reach us.
The same would be true, I think, for any service that is relying on a static IP address for routing - UNLESS BT have done something clever with the allocation of IP addresses.
So, my question remains: will the static IP address somehow get transferred over, or will the 4G backup be of no use in keeping the IP phone connections running? Surely we aren't the first to want to know this?
The 4G backup does indeed carry your static IP in the unfortunate event of your broadband line going down. The fall back into the 4G contingency has been made so less impact has been felt by our customers. If you would like any more information, please let me know
