New single-chip solution for VoIP phones

ESS Technology has released a new chip for VoIP phones which it claims is the first of its kind.

The ES9701 embeds two subscriber line interface circuits (SLICs) along with an Ethernet switch, which ESS believes will provide a high level of integration at a low cost for both VoIP adapters and applications.

Included in its features is a 32-bit RISC processor, an AES encryption module and an LCD display with keypad interface.

Additionally, the ES9701 comes packaged with a VoIP phone/adapter reference design as well as a Session Initiation Protocol (SIP) stack.

Robert Wong, the firm's vice-president of marketing and worldwide sales, said: "The ES9701 enables rapid development of VoIP phones and adapters at the lowest system cost. Finally, we can have affordable VoIP for everyone."

Last month, ClearSight announced that it had added new functionality to its Network Time Machine which can help with VoIP analysis.

The turnkey recorder is now able to support network time protocol servers.
