The Risk of BYOB
Bring Your Own Broadband (BYOB) is not nearly as bad as most carriers claim. Broadvox is one of the few carriers that will support a SIP Trunk providing VoIP service utilizing BYOB. We do this primarily because businesses can become trapped in long term agreements with a carrier and would face high termination fees if they attempted to cancel prior to the end of the contract term.
