Abstract
Purpose
In many settings, the users are mobile (e.g. away from their desks) while high quality multimedia telephony equipment has fixed locations. This may result in unsuccessful multimedia calls and motivates a context aware system which supports session mobility. This paper aims to address these issues.
Design/methodology/approach
The approach is to utilize state‐of‐the‐art in‐context awareness and integrate this into a real time telecom system based on SIP. System requirements are formulated and the system is designed, implemented and (technically) tested.
Findings
The paper contains a thorough analysis of why baseline SIP and SIP REFER alone cannot solve our case and why a new SIP extension is introduced. The solution is evaluated and compared to solutions such as “virtual terminals”.
Research limitations/implications
It is pointed out that the context model does not directly support roaming between two different business domains. This issue is however of limited impact in an enterprise setting. The current prototype is thoroughly tested from a technical viewpoint, but user studies in real organizations are recommended as further work.
Practical implications
The paper shows that human issues and issues relating to computer mediated communication (CMC) are strongly linked to technical details in SIP. In practice this means that researchers in CMC and CSCW should look more into building prototypes where real time conversational features are supported together with dynamic change of media types.
Originality/value
The main value of the paper is a thorough described technical realization of the context aware multimedia application ENriched MEdia (ENME). The background material and the appendix should be of value to anyone interested in convergence between computing and communication.

Abstract
Purpose
Effective Emergency Response Management (ERM) system evaluation is vital to the process of continual improvement within emergency response organizations. The purpose of this paper is to investigate if an entire ERM system can be captured and encoded within a standardized framework.
Design/methodology/approach
Employing an exploratory approach the authors apply a mixed methods case study design and inductive reasoning to analyse documentary evidence provided during the inquest into the London Bombings 2005. The authors use content analysis to investigate the nature of ERM system data availability and apply principals of Network Theory to iteratively develop a framework within which data can be encoded.
Findings
The authors find that complex ERM system data can be captured and stored within a standardized framework. The authors present a conceptual framework and multi-stage mixed methods process, the Standardized Emergency Response Incident Evaluation System (SERIES) model, to support data collection, storage and interpretation. The findings demonstrate that ERM system evaluation can benefit from the adoption of a standardized mixed-methods approach employing data transformation and triangulation. The authors also demonstrate the potential of the proposed standardized model, by integrating qualitative and quantitative data, to support interpretation and reporting through the use of appropriate data visualization.
Originality/value
The SERIES model provides a practical tool and procedural guidelines to capture and share vital ERM system data and information across all emergency services. It also presents an opportunity to develop a large comprehensive multi-incident dataset to support academic inquiry and partnership between academics and practitioners.
