I think you hit the nail on the head:
VoIP makes sense because it can be made into a more 'intelligent' services that follow the user rather than a specific device or location and it can be combined into a rich personal information capability. In reality the service falls short because of user device interface and QoS issues.

Part of the problem is reaching a saturation level with common program and device interface. If VoIP is simply used to replace person-to-person voice calling the only advantage, if at all, is price. If the QoS falls short then that blows it for most users.

You can see the formation of what is likely to make VoIP/SIP and extended messaging and social networking services come together: Google, Nokia, Ericsson among others are building the modular approach that can work across devices and several OS environments and making these available to developers. That should unleash greater ability for individual programs to mesh VoIP and other capabilities more harmoniously. there are already enterprise level VoIP suppliers/integrators who are making the shift and its likely this will proliferate into consumer markets as well.


VoIP services aren't lacking popularity- some statistics put business use at almost half of large (500+ employees) enterprises. Keeping a landline phone system is often a result of the "if it's not broke, don't fix it" school of thought, because these systems DO still work, just not as cheaply or as well as VoIP.

VoIP has a natural place in business because its deployment can be localized and inter-connected via PSTN. the case for use on mobile networks is subject the a more varied use environment including varying latency. While latency, jitter and bandwidth performance can be issues on wired Internet connections and networks connected to traditional voice networks, due to the difficulty of the varying nature of wireless environments, networks must be designed to be more robust to the point of 'overkill' compared to what would be typical for wire line voice or data networks.

But, as suggested previously, market dynamics and synergy within the broad context of ICT developments can change the criteria for a shift to VoIP:
Voice communications, messaging, email, social networking will increasingly work together in a somewhat more seemless array of programs, sites, and aggretations. VoIP better fits into the fabric of development including working with modular social networking frameworks being developed by Nokia, Ericsson, Google, Apple and others.

The technology has to work but it also has to be what is best leveraged by higher level developments.


Hi Mary,

fully agree, in the enterprise market VoIP has come a long way in recent years and certainly had a big impact on prices and features!



I think the main issue is infrastructure.
PSTN/mobile calling is ubiquitous. Not only from the point of quality of service, but from the ability to call from any phone to any other phone.
VoIP is a bit more complex than that (especially mobile VoIP which usually requires downloading and configuration). As long as this is the case, it won't replace today's "legacy" systems. And when it does, it will probably be done by the carriers themselves.
