RingCentral's (News - Alert) plans to launch an initial public offering (IPO) got some new details today, as the exact size and scope was announced, complete with an expected start date in which trades should start selling. The details announced should offer up a good picture for RingCentral going forward, if everything goes as planned.

RingCentral is set to offer up fully 7.5 million shares of common stock, which will be mostly from the company with an additional 80,000 shares being sold by current stockholders. The shares will be made available at $13.00 per share, and can be found starting September 27 under the ticker symbol RNG on the New York Stock Exchange. Reports suggest that the $13 per share was the top range of the expected opening price, as shares were set to run between $11 and $13 per share.

Meanwhile, shares did quite well on the open market, opening for trading at $17.25 per share after the shares were priced, reaching a high of $19.40, before closing off the highs. After hours trading, meanwhile, saw a bit more of a dip with recent numbers putting the share price around $18.16.

RingCentral offered the underwriters a 30-day option with the stock, allowing for the purchase of up to 1,125,000 shares of common stock, and the company has a substantial lineup of both book-running managers—including names like Goldman, Sachs and Co. as well as BofA Merrill Lynch—and co-managers in the forms of Raymond James and Allen & Company LLC.

RingCentral has been operating since 1999, with a focus on cloud-based telephone services, including the standards like fax, text and voice between PCs, as well as offering up services for mobile devices and desk phones as well. At last report, RingCentral boasted 300,000 business customers with a particular focus on the small and medium-sized business (SMB) market, helping the company yield, at last report, fully $114.5 million in 2012, which in turn was up from $78.9 million in 2011. RingCentral had previously raised funding from several sources, a total of over $44 million from several different investors including Khosla Ventures, Sequoia Capital (News - Alert), Silicon Valley Bank and several others.

A company that's been in operation for nearly a decade and a half, and in an area that's pretty much been running about that long, likely has a great perspective on the field as a whole. Cloud-based telephony, and the various components that go into that field, is itself a growing operation, as evidenced by some of RingCentral's earlier numbers. Voip-Info.org, at last report, added RingCentral to its list of the best SIP trunking providers in the field, which gives it still more credence.

The whole thing, meanwhile, adds up to being a terrific potential field for its initial investors, which given the bump upward in the stock value, suggests that there are plenty of parties interested in buying a slice of RingCentral. As RingCentral carries on with further development, meanwhile, more new possibilities are likely to emerge that should give investors extra faith in the company as a whole, and hopefully, continue to add to the stock's value.
