sx200 icp - how to change the direct page from a "ring" to a "ton

[JimHilton]

Hi, On my work system, if I do a direct page, dial the extension, it will make the extension ring once and then you can speak.

On my home system however, if i do the same operations as above, it will make a tone noise instead of a ring.

I can't figure out where to change this. Any ideas?

Thanks
