Scalable network assessment for IP telephony
2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577), 2004Multimedia applications such as IP telephony are among the applications that demand strict quality of service (QoS) guarantees from the underlying data network. At the predeployment stage it is critical to assess whether the network can handle the QoS requirements of IP telephony and fix problems that may prevent a successful deployment.

Assessing network readiness for IP telephony
2002 IEEE International Conference on Communications. Conference Proceedings. ICC 2002 (Cat. No.02CH37333), 2002Networked multimedia applications require stringent real-time QoS guarantees. Successful deployment of such applications closely depends on the performance of the underlying data network. The characteristics and the QoS requirements of these applications are different from traditional data applications.

Resource management for IP telephony networks
IEEE 2002 Tenth IEEE International Workshop on Quality of Service (Cat. No.02EX564), 2003The two key resources in an IP telephony network are the Internet telephony gateways (ITGs) and the IP network. These resources must be effectively managed to simultaneously provide good QoS to calls and maximize network resource utilization. This paper presents two main contributions.

There are mainly two types of used communication systems; circuit switched and packet switched networks. In circuit switched networks, there must be a dedicated path and a sequence of connected links between the calling and called stations. A connection with the proper resources has to be established prior to the start of information exchange.

International Conference on Communication Technology Proceedings, 2003. ICCT 2003., 2004
This paper reviews trends in services, market and technology for IP telephony, which is growing in the international and domestic market. Also enterprise network apparatus are being replaced by IP based apparatus, which enables the integration of Internet and PBX. It also describes technical and regulatory issues for further penetration of IP telephony.

Bridging the gap to IP telephony
Bell Labs Technical Journal, 2002Application of the Internet protocol (IP) as a network technology for telephony has the power to revolutionize the telecommunications industry. The bandwidth is flexible and almost free, and new services can easily be introduced. This abundance of services and bandwidth is the promise of IP telephony.

Emergency Telecommunication Support for IP Telephony
2005As universal high speed internet access becomes a reality, phone calls are increasingly being made over the Internet rather than the conventional PSTN. The danger to this trend is the un-availability of priority mechanisms for communication between emergency response personnel during times of disaster.

Location Information Discovery for IP Telephony
2008The lack of an accepted standard approach to the provision of caller location information is a serious shortcoming in IP telephony. This paper presents a novel approach to implementing this functionality without the additional infrastructure overheads typically found in comparable efforts.
