Reliability – To support their growing business, Pawel Klimecki, NETCOM Network Engineer noted that “maintaining network reliability and scaling are key objectives for our growing business, requiring a redundant SIP architecture for all elements of our network”. This meant redundant call servers and a redundant session border controller solution that could route traffic around a failed call server.
SIP Trunking Routing – Providing low-cost local and international calling access requires working with multiple wholesale carriers. NETCOM chose to work with three separate SIP-based wholesale operators to keep operating costs low and provide high reliability. Directing traffic to three operators requires a means to intelligently route outbound call traffic and detect network outages.
FreeSWITCH Compatibility – a key element required to deliver business services, the FreeSWITCH telephony platform is central to NETCOM’s network. Compatibility with FreeSWITCH was considered imperative when searching for a software-based session border controller.
Protection Against Attack – Addressing the issue of network security, Pawel noted: “To protect their network from potential attack, we knew we needed a session border controller that could protect against denial of service (DOS) attacks, registration floods and other attacks.”
Cost of Operation – As a small organization, maintaining low operating costs are critical for NETCOM. “Open source software and low-cost subscription-based products fit our business plan, allowing us to build our customer base without major up-front costs”.
