Repurposing a UniFi Cloud Key as 3cx border control

[Marduk201]

Hello guys i was wounding if anyone tried to repurpose a gen1 cloud key as a border control we are upgrading a retail store chain to 3cx and have about 3 to 4 phones pre store and was looking for a solution. and then had the idea of loading the border control to an old cloud key that isn't in use for anything for the task. there is no server at any of the stores so was thing of this or a Raspberry Pi. anyone working on something like this.?

So you want to save $50 per store to setup an unsupported configuration?
