We can take their cellphone number that came in… query it against any of the orders in our system... and if there’s an active order we can automatically reply… RingCentral lets our small business act like a big business.

Now when a job candidate receives an SMS message, it comes from the phone number of the recruiter handling that account. People can use that number to call you or text you back.

I think I ran into a couple of problems, but I contacted tech support, and they were resolved right away. I wish a lot more companies had that level of help.
