Customer Scenario – SmartSIP Direct Routing

The Wonder Widget Company, with multiple offices in the United States and Canada, wanted to first route all calls to HQ, regardless of location dialed to more efficiently handle calls via centralized service departments – with calls centrally serviced then sent to the branch offices.

After implementing SmartSIP:

  • Each office has its own DID number, with all calls first routed by SmartSIP to corporate HQ, then connected to centralized service departments, if applicable, resulting in improved customer service.
  • Wonder Widget has also configured SmartSIP to route all calls from overdue customers to Collections, regardless of the individual or department requested, which has significantly reduced DSO.
