IP telephony, a technology that enables voice communication via Internet protocol network, is capable of supporting integration of diverse communication media including voice, data and video, and configuring geographically dispersed systems into one integrated network.

IP telephony, as it can be managed easily through centralized management, can reduce the operational cost including call charges drastically by configuring an integrated network of voice, data and video.
Characteristically, IP telephony is available anytime and anywhere via Internet network unencumbered by limitations of time or space. It can also connect diverse applications organically using open protocol as it heads toward an era of multimedia and ubiquitous communication.

Accordingly, IP telephony is changing our routine communication environment from simple reduction of costs to new driving force of value creation. Based on accumulated technical know-how of past years, ECS Telecom provides IP Telephony Solution that ensures highest quality and stability.
