Thats a lot of users and thats why we are seeing a huge spurt in new companies which are coming up to provide services to these users. And thats the reason most of the information is made available on the web. Let us now look at another statistic.

The reasons are many and I have already highlighted a few in my previous blog post Return of the telephony apps. The main reason is development complexity. It is really hard for developers to create good telephony applications. Thankfully, because of recent advancements in technology and services like Twilio , KooKoo (for India) and other cloud telephony platforms it is ...

Voip was a major disruptive technology for phone service applications. People were able to setup communication platforms and build telephony applicat...
