Hi,Does anyone know what I would need to use as a dial string for an ATA that will only ever need to dial a specific external number?, also would i need to prefix it with 9 for line access?
where 1234567890 is the number you want to dial. Yes you would need to add the external prefix if that's is what's is require to dial out. This is a hot dial setup, going off-hook, auto dial the number.
