SIP
Many SIP-trunking providers deliver a number of value-added services, such as dynamic call re-routing. This lets voice architects set rules for in-bound call management, such as “follow- the-sun” configurations that route incoming calls to call centers based on time of day, or routing of calls based on utilization of existing resources. By moving this routing logic into the service-provider network, customers can reduce their own operating complexity, further reducing costs and simplifying call-routing management.
Many SIP-trunking services also let small and midsize businesses extend their global market presence virtually by providing local access numbers in distributed geographies. For example, a small business with offices in New York could leverage SIP-trunking providers to establish local numbers in London and Munich. Incoming calls to distributed local numbers are brought onto the SIP-trunking provider’s network via its PSTN gateway, then carried back to the customer’s own phone system for termination.
Look for more than just cutting PSTN access costs when evaluating SIP trunking service offerings.
