Switched it off in 2003.. enabled it again in 2005 because of a practical joke by a friend who had my new manager made it a requirement for the new job.. :D

Switched it off soon after again. Reason is mainly that 99.9% of the voicemails left were work related (I only keep one phone# for everything) ahem, "lazy bullshit". It seems most (middle) management is constantly leaving messages about non-issues, for me to deal with. Texting is a miniscule additional "hurdle" which filters this out for me.

I had several discussions proving my point.

  [Bill Lumbergh]"Yeah, could you please enable your voice mail?"
  [Me]"Well, if it is important you can text me, I'll get right back to you"
  [Bill]"but that is less convenient.."
  [Me]"I guess if there is something important, it would warrant the effort to send a three word SMS message.. 'please call me'"
  [Bill]"Eh.."
