IP-Based Small Business PBX
An IP PBX can do everything a traditional small business PBX can do and more. It performs the switching and connecting of Voice over IP as well as landline calls.
A conventional PBX requires two networks, one for data and another for voice. An IP PBX system runs on an IP data network, which saves costs and minimizes network management.
You can use IP phones, softphones (which don't require any phone hardware beyond a computer and a microphone headset), and landline phones on an IP PBX phone system.
Unified Communications: IP PBX and More
Small businesses require specialized features to support their particular workflows. Unified Communications Manager Express from Cisco Systems is designed specifically for small businesses. It combines an IP PBX with robust telephony features that traditional phone systems can't deliver.
Unified Communications Manager Express is affordable, reliable, full-featured, and easy to deploy, administer, and maintain. It helps small businesses dramatically reduce communications and network management costs, enhance collaboration, improve productivity, and more.
