Why interconnect PBXs in multiple sites over the PSTN and maintain separate routing tables in each location when you already maintain an IP connection between each location? OpenScape Exchange allows you to interconnect all your sites using a centralized IP-based call-routing system, and gain immediate interconnection and call-cost benefits without having to incur the large capital costs of wholesale PBX replacements. The financial benefits of IP least-cost routing (IPLCR) with OpenScape Exchange can be considerable, because not only are PSTN interconnection and call costs avoided, but so are all the administration costs of maintaining numbering plans and routing tables in the PBXs.
