Moonie, I've been making phone calls each Saturday to my brother which last an hour as I get the first hour free at weekends 
I could get a slightly more expensive phone package with free calls but I don't for tax reasons. The majority of my business calls are during the weekdays during the daytime so the package with free weekend and evening calls isn't relevant for me. With tax, I can claim the business use of phone based on the value of business calls to private ones. With a free calls package, that becomes trickier to quantify business use.
