As it stands now, Google Voice has great potential, but there are so many basic features missing it is completely unusable for lots of SMBs.
As a consumer, I only want one number to call a business, not several. I also want to be able to text that business when I can not or do not want to talk.
As a business owner, I want my team calling out from one, recognizable phone number. I want our customers to be able to text us with questions... and I NEED my team to be see a shared contact list with history, etc.
I really hope Google Voice gets these basic features soon... It would be hard to beat in the Workspace suite.
