How to straddle this bet - VoIP

I've really been interested in the prospect and growth of voice over internet providing. I like the product and how it has the possiblity of continued growth with their subscriptions to customers and small business as an alternative to exorbitant telephone bills from larger telecoms.

I've only started to look into this. Has anyone invested or considered this in a telecom investment?
