An interoperable signaling solution between SIP and H.323
(Telkom, 2001)
The Session Initiation Protocol and H.323 dominate the Voice over IP world. These signaling protocols are responsible for call setup and call tear down by IP telephony solutions. This project analyses and discusses the ...
A framework and toolkit for the collection and analysis of QoS statistics for voice traffic in Next Generation Networks
(Telkom, 2000)
The multi-service, multi-architecture nature of NGNs is so complex that the management of services, in addition to networks, emerges as a research challenge. Despite QoS limitations, VoIP (as opposed to VoATM), dominates ...
Web-based telephony bridges for the deaf
(Telkom, 2001)
A Teldem provides text-based telephony services to the deaf. Despite an array of text-based communications mechanisms on the web, the Teldem is the only means of synchronous telecommunication available to a deaf person. ...
Development consortium: HCI across borders
(Association for Computing Machinery, 2016)
Though every country and context is unique, and much
of HCI research aims to design for situatedness, there
are lessons to be learned across borders, across
contexts. Questions we ask include: What are common
themes ...
Tuning a mid-range rural WiFi-based mesh network
(ACM, 2013)
Little is known about how mid-range, or several km, dis- tances a ect multipoint-to-multipoint links when single ra- dio nodes with omnidirectional antennas are used. In this poster, a real network with these characteristics ...
Information protection in video relay services
(ACM, 2013)
This work in progress paper reports on initial research into the protection of information of the individuals that make use of video relay services. Our research team has developed an application called SignSupport, to aid ...
Unmasking community trust issues in rural field work
(ACM, 2013)
The principal objective of this paper is to describe the au thor's fieldwork and research in a remote rural area of South Africa, where a Village Telco is deployed to provide Voice over Internet Protocol on a wireless mesh ...
Deaf telephony: community-based co-design
(Wiley, 2011)
The process of community-based co-design is one that explores various solution configurations in a multi-dimensional design space whose axes are the different dimensions of requirements and the various dimensions of designer ...
Situation-aware routing for wireless mesh networks with mobile nodes
(IIMC International Information Management Corporation, 2012)
This paper describes a situation-aware algorithm based on the current situation of a mesh network with mobile nodes that improves quality of service. After running laboratory performance tests, we concluded that a ...
A Softbridge with carrier grade reliability using JAIN SLEE
(Telkom, 2004)
We have built a SoftBridge prototype within a JAIN (Java APIs for the Integrated Network) SLEE (Service Logic Execution Environment). A SoftBridge is a semi-synchronous multimodal IP (Internet Protocol) -based communication ...
