In 2006, in preparation for an initial public offering, Michael Snyder, former president of ADT Security Services replaced Vonage co-founder Citron as the organization's CEO.[19] Citron could not preside over the IPO because he was permanently barred from associating with any securities brokers or dealers.[20][21][22][23] In 2007, in a restructuring effort to reduce ongoing net losses in the face of double-digit stock price slips and patent infringement issues, Snyder resigned, and Citron returned as interim CEO.[24] The company announced plans for 10% layoffs as it secured $215 million in financing.[25]

Vonage offered shares of its stock to its existing customer base in the period before the initial public offering.[26] Under normal circumstances, only large institutional investors such as banks are able to buy shares of an IPO.[27] Vonage's initial public offering occurred on the New York Stock Exchange on May 24, 2006, opening at $17 per share.[18] The price closed at $14.85, a decrease of 12.7 percent, the worst trading day for any IPO in 2006 up to that point. The IPO raised $531 million for the company. However, the existing customers who lost money filed a class action lawsuit.[28] The IPO and its immediate aftermath also earned Vonage a Business 2.0 Magazine award as 14th of 101 Dumbest Moments in Business for 2006.[29] In 2009, Vonage reached an agreement with the IPO investors. All shareholder claims against Vonage and its individual directors and officers who were named as defendants were dismissed.[30][31] The amount of the settlement, $3.6 million, was paid by an insurance policy covering the directors and officers of the company.[32][33][34]

The firms underwriting the IPO, Citigroup, UBS, and Deutsche Bank, were fined a total of $845,000 and ordered to reimburse customers for "failure to adequately supervise communications" with investors.[35] NYSE regulators went so far as to investigate possible short-selling.[36]

Beginning in 2013, Vonage acquired several companies as it refocused its business from a home phone provider to a global business cloud communications provider, including:[37][38][39]

• Vocalocity, a software as a service (SaaS) provider of cloud-based communications services, for $130 million;[40]
• Telesphere, a unified communications as a service (UCaaS) provider to large companies, for $114 million;[41]
• iCore Networks, also a UCSaaS provider to large companies, for $92 million;
• SimpleSignal, another UCSaaS service provider to small and medium-sized businesses, for $25 million;[42][43]
• gUnify, also a cloud-based communications service provider to businesses (price not disclosed).[44][45][46]
• Nexmo, the 2nd largest CPaaS company, for $250 million;[47]
• TokBox, a WebRTC programmable video provider, for $35 million.[48]
• NewVoiceMedia, a Contact Center as a Service (CCaaS) provider, for $350 million [49]
• Over.ai, a Voice and Conversational AI provider for enterprise communications [50]

On 22 November 2021, it was announced that Vonage would be acquired by Ericsson in a US$6.2 billion all-cash purchase.[51][52] The acquisition completed on 21 July 2022.[11] According to the press release, Ericsson will acquire all of Vonage's outstanding shares at an all-cash price of US$21 per share, a 28% premium. The acquisition will be financed through Ericsson’s existing cash resources, which amounted to SEK 88 billion as of 30 September 2021 on a gross basis, and SEK 56 billion on a net basis as of the same date.

Vonage will then become a wholly owned subsidiary of Ericsson but will continue to operate under its existing name and be reported as a separate segment in Ericsson accounts. Vonage's employees will remain with the company and the Vonage CEO Rory Read will join the Executive Team of Ericsson, reporting to CEO, Börje Ekholm.

Vonage offers two unified communications platforms for businesses that integrate communications services, such as video conferencing, voicemail transcription, and desktop sharing, using voice as a platform. Cloud communications services allow business customers to connect with various business applications and customer relationship management (CRM) tools through a middleware technology.[66][67] For business customers that rely on high quantities of voice, video and data communications in their day-to-day operations, Vonage provides quality of service over its own private Multiprotocol Label Switching (MPLS) network and via a Software Defined Area Network (SD-WAN) product.[68][69][70][71]

Residential services provide home phone plans using VoIP (voice over Internet Protocol) over a broadband Internet connection, such as cable Internet service or DSL. Features for Vonage home phone residential service includes voicemail transcription; 411 calling; caller ID; call waiting; do not disturb; and a network availability feature which forwards all calls to a mobile phone if Internet connectivity is lost.[72][73][74][75] Many of Vonage's residential products offer international calling plans.[76]

Vonage customers must have a broadband Internet connection, such as cable Internet service or DSL, through an Internet service provider (ISP). To initiate subscription a customer must provide a billing and shipping address in the country of service. Vonage supplies an analog telephone adapter which connects a customer supplied standard analog telephone to the Internet and the Vonage service.[77] Residents of the U.S., Canada, and the UK may subscribe to Vonage by credit card from their respective country, but the Vonage adapter can be connected to the Internet anywhere.

Usage is generally referred to as "unlimited", though Vonage has different national "fair use" policies limiting Vonage-to-phone calls to a few thousand minutes per month in the UK,[78] Canada,[79] and U.S.[80] Evidence suggests that calls are limited to a length of 3 hours and 56 minutes.

Subscribers may choose a number in the country of the service they subscribe to for their primary line, in an area code of their choice. Subscribers can obtain additional "virtual numbers" for a monthly fee. Vonage also offers virtual numbers in Mexico, Canada and Europe. While the company supports porting a U.S. telephone number via the FCC's local number portability (LNP), not every phone number is available in every area code. Additionally, customers can transfer an existing number to Vonage, which can take up to 7 to 10 business days from the time the customer completes the Number Transfer Authorization (NTA).[81]

Vonage offered 911 service on a VoIP platform for the first time in 2003.[82] For 911 location services to work, subscribers must activate the 911 calling feature by registering their full address with the company. Customers are responsible for maintaining their 911 location information at all times.[83]

If a customer dials 911 before the 911 verification is completed, the call will usually be routed to a national 911 call center where basic information must be given (name, location, nature of emergency, etc.), after which the call is transferred to a local public service answering point, like a local Police Department.[84][85]

VoIP service relies upon consistent broadband-ISP uptime and VoIP-equipment compatibility with the ISP's modem. Although VoIP was initially optimized for voice, some fax equipment can be operated over VoIP,[86][87][88] but compatibility of monitored alarm systems and other devices is less certain.[89] Vonage offers "specially commissioned" Fax Line service.[90] Vonage recommends customers keep a basic traditional landline dedicated to their home alarm system and use Vonage for the rest of their calling needs.[91]

Vonage implements Voice over IP sending audio via RTP and signaling via SIP.[92]

In March of 2023, The Vonage Foundation entered into a partnership with Girls Who Code to help provide accessible coding education opportunities to women of all ethnicities and backgrounds by sponsoring their Summer Immersion Program 2023. The program focuses on creating a more diverse workforce in the technology industry by providing virtual classes for high school STEM students for free.[93]
