Network-based telephony using VoIP — that’s voice over Internet Protocol (IP) — is where the future of telephony lies. But, before, VoIP meant settling for fewer phone features than on a traditional system. Now, ESI’s changing all that forever.

The IP Series systems — the IP 200 and IP 40 — are advanced, network-based business phone systems that combine the best of both the telephony and data worlds:

• The rock-solid performance and all of the telephony features of ESI’s acclaimed IVX^® Series systems;
• The state-of-the-art delivery of packetized voice via the existing local area network/wide area network (LAN/WAN) to the desktop.
