The question is being asked “what are ISPs doing about voice?” This is particularly relevant as the market consolidates and B2B ISPs not only seek economies of scale but additional sources of revenues.
Timico was founded as a fully converged ISP from the outset. Early on we had to decide whether to simply white label services from other ISPs and ITSPs or do “get into manufacturing” and do it all ourselves.
At the outset there were no real white label VoIP options. You had to do it yourself. However there were plenty of ISPs providing Virtual ISP services.
