Voice over IP (VoIP) defines a way to carry voice calls over an IP network including the digitization and packetization of the voice streams. IP Telephony utilizes the VoIP standards to create a telephony system where higher level features such as advanced call routing, voice mail, contact centers, etc., can be utilized.
Migrating from TDM to VoIP
NetEngine IADs from Verilink provide a migration path from TDM to packet deployments. For example, a T1 IAD deployed today in a channelized TDM application can be reconfigured to support VoIP. There is no additional cost. No hardware cost, no software cost, simply a unit reconfiguration that can be performed remotely.
