Pros / Cons
  • What I like most about Google voice is that you get all the features of a regular phone number for free with Google voice's virtual phone number, mostly the ability to receive verification codes
  • It screens calls and doesn't always let calls through, and the sound quality isn't always the best on both my end and theirs.

  • It was nice to get a trial and test number to make sure everything was working before purchasing the trunk with 3 channels
  • so far terrible service, with little to no feedback.
