It appears that several mid-sized VoIP companies are failing to realize their potential and being edged out of the market. One of the biggest of these companies is Jangl, a VoIP business that began by offering anonymized online calling and then moved on to the development of click-to-call VoIP widgets for social networking sites. Despite having done moderately well in these areas, the venture capitalists backing the business aren’t interested in continuing their support. Talks of acquisitions came to a standstill this week and major players in the organization resigned. It appears that many of them are going to be moving over to work at Jajah, a company that has done significantly well for itself in the VoIP industry over the last year or so. It is unclear what will be happening with Jangl at this time but it seems safe to say that it’s not a name we’ll be hearing much of anymore.
