System is as reliable as the old-fashioned network

Question

Explain briefly that the system is as reliable as the old-fashioned network?

Answer 1

Early on VoIP services frequently sounded tinny, delayed or digitized. In current years, the technology has gotten greatly better, and it is stated that it won't be long before it accomplishes the tech industry's vaunted ‘five 9s’ level -- 99.999 percent dependability. For now, VoIP might not be perfect; however cell phones have made people more compliant of less-than-ideal sonic circumstances.
