Hi,

We're trying to setup a cloud based PBX for Alestra, an ISP in Mexico, and we keep encountering this error and can't figure out what the problem is.

Hello @geektronics

The redacted public IP the error is coming from, does that belong to the provider or the PBX? Did you use the included template to add the provider to the PBX?
