Integrating voice / video communication into business processes can accelerate resolution time, reduce mistakes, and establish a full audit-trail of the interactions. Some VoIP service providers offer website based or plugin based solutions, which are, however, difficult to integrate with other applications.

Whilst SAML-based federations are most often used by academic and semi-commercial institutions that focus only on attribute-based authentication, we foresee a growing interest for service providers providing charged services. Since more and more academic and semi-commercial federation participants offer Voice-over-IP (VoIP) services, this type of service provides an entry point into identity federation...
There are several uplink scheduling algorithms in IEEE 802.16 systems, such as unsolicited grant service (UGS) and real-time polling service (rtPS), which can be used for voice over IP (VoIP) services. But these algorithms have a problem of energy wasting. To solve this problem, we propose an energy saving based uplink scheduling algorithm for VoIP services. Then we analyze the performance of the...
