Sky Talk Anytime Extra

[DebbieChandler]

Below is Skys 'Acceptable Use Policy', i am planning on getting sky but what is deemed as 'exceeds that reasonably expected' how many hours a month? 250hrs? before they cut the line?

"Sky Talk call packages are provided for domestic purposes only and must not be used for any business or commercial purpose.
If your use of 'unlimited', 'free' or 'no-charge' calls provided as part of your Sky Talk package exceeds that reasonably expected of a person using the service for domestic purposes"

All answers greatly appreciated.
