VOIP
Voice over IP, one of the most well-known and used cloud telephony services, refers to a specific use for Internet Telephony allowing for the transfer of voice data using an IP network.  Telephones are connected to data ports on the IP network. VOIP systems usually interface with the traditional public switched telephone network to allow for transparent phone communications worldwide. Skype is probably the most well-used internet telephony services of this type.


VOIP services can be bundled together with other communications services such as broadband, hosted email and messaging services. Uptake of VOIP in the business sector has been relatively slow owing to perceived lack of Quality of Service (QoS) guarantees and a limited understanding of what benefits VOIP can bring to businesses. Comparatively, in the consumer space where such factors have not been issues, individuals have been quicker to adopt VOIP applications. Certain VOIP providers, e.g. Skype, have also integrated SMS into their communications portfolio.

VoIP and Mobile Number Portability:
Mobile number portability (MNP) has been a key part of introducing free competition between networks into the mobile space. MNP hasn't, however, been without its problems. Every phone number is associated by the mobile phone networks with a particular operator and, when a subscriber switches a mobile operator, the routing of voice calls and SMS becomes more complex.
 
The problem for VOIP arises when a call is to be terminated at a mobile number that has been ported from its original network. In a system where MNP is in place and there is no centralised database of numbers, the VOIP provider can no longer use the "network root prefix", which identifies the number's original operator, to identify the appropriate routing and so must look to other ways of accurately routing the call.
