BUSINESS SUMMARY
One of the primary challenges faced by service providers in delivering
quality voice communications is the elimination of the hybrid echo that
occurs due to the 4-wire to 2-wire convergence point in wireline networks.
Wireless and VoIP networks must also be protected against hybrid echo,
as they typically interconnect with the wireline network.
Hybrid echo cancellation is becoming more difficult due to the network
migration from circuit to packet technologies that increase delay. Ditech
Networks’ industry-leading 192 ms hybrid echo tail delay feature completely
cancels echo, even in extended delay situations.
