A word from Kaufmännische Krankenkasse – KKH

  • “Oracle’s Acme Packet Net-Net Enterprise Session Director helped us deploy our session initiation protocol (SIP) trunking service by enabling seamless integration with our Cisco Unified Communications systems and manipulating SIP signaling content as we need it. With Oracle’s Acme Packet solution, we took an important step toward creating a more extensible telephony architecture that ensures support for future needs and value-added services, while being more cost efficient than conventional public switched telephone network technology.” – Steffen Ninebuck, Network System Engineer, Kaufmännische Krankenkasse – KKH

  • Reduce operational expenses by decreasing public switched telephone network (PSTN) transfer fees and overall costs
  • Incorporate all customer service centers with existing unified communications infrastructure by transferring internal and external calls directly to the company’s private Internet Protocol (IP) network
  • Reduce risk of telephony outage by deploying a high availability cluster infrastructure with full redundancy, linked to the telephony provider
  • Improve business flexibility by maintaining full control over all incoming and outgoing calls


  • Reduced telephony-related expenses by more than 20%—without compromising security, reliability, or service quality—by replacing conventional PSTN circuits with a centralized session initiation protocol (SIP) trunking service that provides more cost-effective PSTN connectivity
  • Enabled straightforward integration with the company’s Cisco Unified Communications Manager environment, leading to improved service agility for the IP-based contact centers with unmatched architectural flexibility and multivendor interoperability
  • Protected the organization against service-impacting events—such as service theft, malicious attacks, and system overloads—by utilizing enterprise session border controllers (E-SBC) designed to shield and control real-time voice, video, and unified communications as they traverse IP network borders
  • Implemented Oracle’s Acme Packet Net-Net Enterprise Session Director E-SBC to optimize IP telephony performance and reliability by load-balancing session initiation protocol (SIP) traffic and strategically rerouting sessions around equipment or network failures, helping to improve service quality for the company’s service centers across Germany
