VoIP

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.
Session Initiation Protocol (SIP) is a peer-to-peer, multimedia signaling protocol developed in the IETF. SIP is ASCII-based, resembling HTTP, and reuses existing IP protocols (DNS, SDP, etc.) to provide media setup and teardown. Since its first publication in 1999, SIP has generated a high level of interest in the VoIP industry, and many people believe that SIP will become the de facto standard protocol for future voice networks

333Six Steps To Prepare Your Network For VoIP
Deploying new technologies on an enterprise network is always a challenge — balancing cost versus benefits and integrating them with the existing the infrastructure. And Voice over IP is no exception. Deploying VoIP service provides cost savings and end user benefits, but deployment itself can cause many call quality and network related headaches if not planned and implemented properly.
In order to help enterprise network planners and administrators successfully deploy VoIP, Telchemy has developed the attached "Tech Note: Six Steps To Getting Your Network Ready For Voice over IP" (URL: www.telchemy.com/appnotes/TechNoteSixStepVoIP.pdf)
The document provides a six step methodology, including pre-deployment testing and network readiness assessment for use when preparing an existing network for VoIP service. It also contains useful problem descriptions and related information to help alleviate or significantly reduce call quality and network performance problems both during and after deployment.
