But while many wholesalers have made a boatload on what many label "VoIP arbitrage" over the past half decade or so, as large telecom's such as AT&T enhance their respective service offerings, competitors must advance their value propositions from strictly cost-effective pricing structures to include an increasing number of value-added services or risk being passed over in favor of the big boys.

Although many consumers have been drawn in by VoIP's cost efficient characteristics, the next wave of growth, despite being somewhat apparent, may take a bit more to incite. I think that many consumers need to be compelled to use VoIP as an alternative to traditional telephony.

Bundling features with other industry players, enhancing security and call quality are all areas that many lower-tiered suppliers should be focusing on now, before the big telecoms swallow up all of the guppies.
