I'm not the above poster, but I also use voip.ms. I don't think you'd need any software at all to set up a phone number with voicemail that mails the recordings. If you want to place calls from your provisioned phone number, you'd of course need either a VoIP phone, VoIP software on your computer or mobile, or rely on DISA (dialing in to voip.ms's system then entering a number to dial). I use a SIP desk phone, have calls forwarded to my mobile, and also get voicemail recordings in mail. (Going back to the original article -- I can't say if this actually protects you from such tracking. Maybe stalkers could find your actual mobile number by some other means, or for all I know customer-identifying parameters could be used without even knowing the phone number.)
