In addition to Truphone, service providers such as Rebtel, Gizmo5 and others route calls directly to the Voxbone gateway and charge nothing to complete calls. However, traditional operators charge fees to route calls to iNum numbers. Truphone and Voxbone advise customers to verify the fees that apply when dialing iNum calls routed via traditional operators
