Do you think people will be satisfied with Over The Top (OTT) calling solutions like Skype or Google Voice that lack Quality of Service controls, or must broadband wireless operators invest in the solutions with guaranteed QOS?
asked by John Morfit over 2 years ago

Skype and Google Voice are telephony solutions in the category known as Over The Top (OTT). That is, they are pure IP solutions that are ignorant of the underlying bearers. As such , they lack any method of guaranteeing Quality Of Service. The alternative for mobile wireless communications is IMS-based solutions such as Voice Over LTE (VoLTE), that provide guaranteed QOS by ensuring that the underlying bearers have a guaranteed bit rate, moderate packet loss, and low latency. On the other hand, KDDI (Japan) is offering Skype. MetroPCS (USA) initially announced they would offer only OTT solutions, but has flip-flopped after making field trials and will soon offer VoLTE.

John, As for the LD services via VoLTE, I assume international LD. Right? If yes, how will the carrier at the other end with LTE service handles it?

Skype has been around for almost 10 years I think. If no operator has bothered to invest in a solution to improve the quality of skype like calls yet, I doubt anyone will tomorrow. I think they know the cost associated to it is not justified.

Satisfied 100%? NO! We love them because it's free and easy. So, better than paying for it or better than nothing.

Should the broadband wireless operators invest in the solutions with guaranteed QOS? If the carriers make such an investment, they will have to charge the consumer something. I doubt it will be free. So, we are back to square one. If the operator can build this and give it for free and manage to cover up the cost of the service from somewhere else, then hell yeah!
