Here is why you want to choose fiber optics over internet-based VoIP phone connections: Fiber optic lines are strands of thin pure glass that carry digital information over long distances. (They are also used in medical imaging and engineering.) Fiber optic is considered extremely reliable and that is why it is used by so many toll free phone service carriers. All calls made to toll free phone numbers acquired from Tollfreenumber.ORG go through fiber optic lines. This technology reduces the number of dropped calls and bad connections. When investing in your own toll free phone number, it is advisable to deal with a provider than can offer fiber optic technology.
