What does the software or service do well? Because I only have a cell phone and no land line, I love having Google Voice for a separate work number. I'm a solopreneur, so it's nice to not hand out my personal number to everyone I meet. It's also terrific to have voicemails and text messages emailed to me, in order to manage everything. Another fantastic service from Google!
What does the software or service not do well? The transcriptions aren't always very accurate, particularly when people leave their callback number. I usually have to listen to the message to get it right. And for some reason, it often breaks up text messages into multiple emails.
What do you wish you had known about the software or service before using? Nothing. It's very easy to set up and use.
Have you used a competitor to the software or service? If so, how does it compare? I haven't used anything else.
