RingCentral is a Web-based telephone and fax service for professionals and small businesses. When you sign up, they provide you with a toll free (800, 888, 877, 866 or vanity number) or a local phone number that you can have all your existing phone lines transferred to.
It’s like Google Voice on steroids because they give you advanced features not found in traditional phone answering systems. For example, you can provide callers with a menu system that does things like: “Please press 1 for technical support, 2 for sales or 3 for billing”. There is also a powerful call answering rule system that will give you the ability to route incoming calls to voicemail, certain extensions, or other numbers based on time of the day, the number they called or caller id. The service can be setup to play special greetings, background music or ads based on the same criteria. There’s even a Free iPhone app version that includes 60 minutes a month.
You can sign up for a free trial and if it works for you and you want to continue, the packages start at $9.99 per month. Right now they are offering a 50% savings deal on the first 3 months of service.
