State of the MGW Market VoIP adoption
State of the MGW Market No one likes a mature market! • Little to no growth • No innovation • Very high cost pressure Who is providing growth and innovation? • Session border controllers (packet to packet) • Wideband codecs for IP and mobile communication • Advanced services such as video • What’s next?
Designer’s dilemma… “I need to design a cost-effective MGW today so that I can evolve quickly to support tomorrow’s features”
Ideal solution – Software licensing Use key files to enable features or capacity Similar to well-known FlexLM™ FPGA companies have started providing similar firmware locking capability Hardware and software vendor must be the same • Hardware assisted key management
