Enterprise Voip can be used in any size organisation, making it applicable for both small and medium business users. If you are looking to break into a foreign marketplace and this involves a high volume of calls with potential clients or suppliers, Business VOIP may be the best way of maximising your international business contact potential without increasing your expenditure. Because VoIP uses the Internet to send calls, the location of your original call is irrelevant, as the proximity to the destination cannot be determined, thus avoiding the long distance charges that would normally be incurred on a traditional landline.
