The company believes that it can build on its 4G and 5G networking technology by taking advantage of the key pieces of the Vonage family.

2020. Business Phone system OpenPhone raises $14M



OpenPhone, the company, which is looking to bring to our work phone the same modern communications features that we use every day, has raised $14M Series A. OpenPhone lets employees make calls, send texts and add context to their business contacts all from an app on their phone or computer. Moreover, the app lets an organization work collaboratively across the platform. For example, a company or department can have a single shared number, as well as their own individual numbers, and can also share and sync information about contacts across the org. There are, however, several competitors looking to bring the work phone into the 21st century alongside OpenPhone. RingCentral and DialPad are just two that also put the work phone in the cloud


2020. Aircall raises $65 million for its cloud-based phone system



Aircall, which is is building a software-as-a-service company around phone calls has raised a $65 million Series C round. When it comes to product, Aircall wants to differentiate itself from traditional call center solutions thanks to integrations with third-party services. For instance, you could see your call information in your CRM to see if somebody on your team has already followed up on a lead. Or you could initiate a phone call from Zendesk if there’s an urgent support request.


2019. Vonage brings number programmability to its business service



Vonage launched number programmability for its business customers. What this means is that enterprises can now take any VBC number and extend it with the help of Nexmo’s APIs. To enable this, all they have to do is toggle a switch in their management console and then they’ll be able to programmatically route calls, create custom communications apps and workflows, and integrate third-party systems to build chatbots and other tools. In terms of those capabilities, users can pretty much do anything they want with these calls — and that’s important because every company has different processes and requirements.


2018. Vonage acquired cloud-based contact center startup NewVoiceMedia



Cloud-based unified communications provider Vonage acquired NewVoiceMedia, a UK startup that builds cloud-based contact center solutions, for $350 million in cash. On the other hand, the deal will help Vonage increase the services it provides, and thus the margins it makes, in a wider suite of value-added IP services — which today include office phone systems, marketing automation and an existing call center solution, as well as MPLS and other IP services. Specifically, it gives it the platform to integrate also more deeply with other software providers like Salesforce, an important part of how Vonage sells its services to would be customers. Vonage claims NewVoiceMedia is the largest privately-owned, pure-play, cloud contact center company globally, with some 700 customers mostly in the mid- to large-enterprise range, including Adobe, Siemens, Time Inc., FundingCircle, and Rapid7.


2018. Dialpad acquired AI-startup TalkIQ



Dialpad, the business communications platform, has acquired TalkIQ to take an injection of artificial intelligence. TalkIQ can capture voice in near real time and apply sentiment analysis and analytics. This could provide a customer service operation with feedback in real time along with advice for managers when to intervene in a call. The TalkIQ functionality will be incorporated natively right into the Dialpad suite of apps, which includes voice and video along with customer service call center management and UberConference for conference calling.


2016. Aircall launched mobile apps for its cloud phone system



Aircall, the service that lets you generate virtual numbers in many countries around the world and share these numbers with your team, just launched its mobile apps on iOS and Android out of beta. With the new mobile apps, Aircall customers can receive or make VoIP calls directly on their phone without having to be tied to their desk. Compared to other customer support software, Aircall already doesn’t require any proprietary hardware and uses a software-as-a-service model. Aircall lets you share contacts and schedules, assign calls to particular team members and track exactly what’s happening. It’s a great way to know whether your coworkers have dealt with a client already.


2015. Cloud PBX Switch integrates with Office 365



Switch, a cloud-based business phone service, now integrates with Office 365 after working previously with Google Apps. Whenever a Switch user receives a call, it will route to a specific destination based on some rules that businesses place. Switch end-users will see additional information like recent emails and LinkedIn profiles for the callers when they receive them. Office 365 users can sign into Switch through the service, which then is able to pull in that data from Office 365 services. The goal for a company like Switch is to basically replace the routing services that companies like Cisco have run. Those services tend to focus more on desk phones and can be a bit clunky to use — though, to be sure, companies like Cisco are massive and could throw their weight behind projects that could compete with a service like Switch.


2015. Switch.co launches phone system for Google Apps



Switch.co, a new, cloud-based phone system, is now becoming generally available for any businesses after the closed beta period. Switch is built to provide unified text and voice communications to enterprise users across a wide range of devices. Switch takes the pain out of employee phone provisioning by integrating with Google Apps and tying each number to an employee’s Google account. It enables a company’s employees to have a single number that would ring on their desk phones, mobile phones, and even on their desktop computers. It also provides a way for them to send messages, as well as share documents and calendar items, so that users within the same organization can have greater transparency around whether or not someone is online and available. Switch costs just $15 per month per employee and offers unlimited calls and texts.


2014. 3CX acquires videoconferencing provider e-works



3CX, the developer of popular Windows VoIP PBX 3CX Phone System, announces the acquisition of Italian video conferencing developer e-works.  In October 2013 3CX partnered with e-works to use its engine for the own videoconferencing solution 3CX WebMeeting. And now they decided to completely buyout this engine. "The acquisition and much anticipated launch of 3CX WebMeeting will significantly extend our lead in the Unified Communications market. With e-works’ cutting-edge technology we will also capitalise on the growth of WebRTC" said Nick Galea, CEO of 3CX.


2011. Panasonic offers Cloud PBX instead of hardware



Panasonic is a world leading manufacturer of PBX hardware for small and medium businesses. And this company is quite satisfied with today's state of things. But the market dictates new terms: the cheap virtual PBX are gradually replacing the expensive hardware systems. So Panasonic is introducing its own SaaS service Panasonic Cloud, which is available only in US so far. It's a fully featured telephone system delivered from the Panasonic cloud. However, unlike most virtual PBX providers, Panasonic doesn't want to completely replace equipment by the service. In order to use the Panasonic Cloud company should buy at least one base station and one wireless ip-phone. The number of phones can be increased to 8. And all of them are programmed to work only with Panasonic Cloud, and if the company wants to move to another SIP PBX provider, it will not be able to use these phones.


2011. Microsoft unplugs Skype from Asterisk



Today Digium (the developer of the open-source PBX-platform Asterisk) has notified its customers that the sales of its product Skype for Asterisk will be terminated since July 26. Recall, Skype and Digium released this Skype for Asterisk connector back in 2009. It allows companies that use Asterisk-based PBX-systems to integrate them with the Skype network and make / receive Skype-calls using the regular office phones. But the new Skype's owner Microsoft, of course, has no particular desire to support the free Asterisk, that competes with its own product Lync (MS Communications Server). So Microsoft decided not to prolong the contract with Digium. Digium assured that existing Skype for Asterisk users will be able to use their Skype-channels during two more years.


2010. Lync 2010 becomes social



Oh, we didn't rename our products for so long time, thought people in Microsoft and decided to rename MS Office Communications Server to Lync. The new version Lync 2010 with a status "release candidate" is already available for free download and contains a large number of new features as compared to OCS. Most interesting are social features, that we used to see more in social networks rather than in VoIP-solutions. First, the activity feeds that you can subscribe to view contact's status changes. Like in the location-services, Lync can determine the actual contact location by the network point to which he is currently connected. People search allows you to find the right person in the company by name and by the area of expertise. Another interesting feature - context call that allows users to push the conversation subject before making a call, so the contact could better prepair to the conversation.


2005. Microsoft to debut Web-based Communicator

Microsoft unveiled Web-based version of its Communicator enterprise messaging software in order to offer customers increased flexibility in accessing the company's collaboration and communications tools. Dubbed Microsoft Office Communicator Web Access, the software aims to help provide customers with an additional option for accessing the software giant's corporate IM system. The company plans to introduce the latest desktop version of Communicator, labeled Microsoft Office Communicator 2005, sometime before the end of June, and has already begun manufacturing the product. According to Microsoft, using Communicator Web Access together with the company's Live Communications Server software will allow workers to access its IM system from any device connected to the Internet. Gupta called the introduction the next step in Microsoft's plan to provide "ubiquitous access to rich presence and an integrated communications experience."


2003. Microsoft launches Office Live Communications Server

Microsoft is set to begin its most aggressive effort yet to sell instant-messaging services to corporations. While MSN Messenger continues to gain Web users outside the firewall, Windows Messenger became the foundation for Microsoft's loftier plans- its new business IM product - Office Live Communications Server 2003 (LCS). Here's a glimpse at what LCS can currently do: Imagine that an employee receives an Excel spreadsheet a co-worker authored. With LCS, a SmartTag appears under the author's name that allows the employee to right-click on the link in order to check the author's online status. The author may be out to lunch, or perhaps, the author is online, whereupon the employee can then launch an IM window and send the author a message. The company will charge $733 for the server software and a $25 client license per person for large-scale buyers. LCS will not work unless the company is running Windows Server 2003 software.


2003. Lotus Notes 6.5 features Lotus Sametime integration



The new version of Lotus Notes 6.5 adds integration with the enterprise messenger IBM Lotus Sametime. From now Lotus Notes client users will be able to see the current online status of their colleagues and start chat with one click for example right in the address book. In addition, with the help of new Lotus Domino Designer 6.5, developers can embed the online status and chat feature in custom apps built on Lotus Domino platform.


1999. Lotus ships enterprise messenger Lotus Sametime

Today, IBM unveiled Lotus Sametime, the solution designed for instant messaging and collaboration over the Internet. The solution is built on Ubique aquired by IBM and consists of Sametime Connect Client and Sametime Server. The Lotus Sametime functionality includes a online status monitoring, instant messaging and object sharing, which allows to simultaneously work with documents and applications over the Internet like in Microsoft NetMeeting. The server costs $ 5,000 and client license costs $20 per user. Lotus Sametime is available as a standalone product or as a component of Lotus Notes / Domino.
