Review Microsoft guidance regarding Media Bypass http://technet.microsoft.com/en-us/library/gg412740.aspx Straight forward in a centralized (single site) topology without WAN links. More complicated in a distributed topology with one or more branch - check the following: Media Bypass shall only be utilized between WAN sites without bandwidth constrains Media Bypass and Call Admission Control (CAC) are mutually exclusive Media Bypass mandatorily requires all media to be represented by a single IP address – the reason why in the above example a Media Termination Point (MTP) has to be inserted.

USA Today. http://www.usatoday.com/tech/news/2001-06-21-teens-im-lasting.htm By Karen Thomas, USA TODAY Breaking up. Making up. Making plans. Asking out. Saying "hey." From the mundane to the emotionally charged, there are no limits to the ways today's kids connect and bond over instant messages (IMs) — those pop-up text windows used for carrying on real-time conversations online. "It's not just empty chatter. They're using (IMs) to have difficult conversations — someone's talking behind your back and you want to confront them," says Amanda Lenhart of the Pew Internet & American Life project. Its survey, out Thursday, finds that nearly three-fourths of online kids ages 12 to 17 rely on IMs to keep in touch with friends. Caroline Barker, 16, is among 35% of teens who use IMs daily; she chats with about 10 close friends and 50 acquaintances in the Bethesda, Md., area. "It's especially good for making plans, or if you're just bored," she says. "It's a given that everybody has it," adds her friend Valerie Hutchins, 15. These Maryland friends IM while doing homework, talking on the phone and watching TV. And they offer insight to the complex social rules that come with a form of communication that still has many adults bewildered.

    Integrating Business Processes with Microsoft Lync & Skype for Business A Knowledge Guide by MindLink Software Contents Introduction 3 Barriers To Decision Making 3 Removing Barriers By Leveraging Real-Time Messaging 4 Making Information Accessible 5 • Pull • Push • Command Unleashing The Developer In Everyone 6 Worked Example – Integration With A 7 Marketing Automation Tool Mitigating Risk While Enabling Fluid Integration 10 What Is Mindlink™ 11 Mindlink Suite 11 Introduction Making decisions is hard. Making the right decisions without all the right information is harder. To make effective choices you need everything that matters in front of you, or at the very least you have to remember everything in context. Today’s businesses can’t settle for scattered sources from disparate systems that require manual searching, analysing and collating when it can all be delivered to their feet when they need it. Barriers To Decision Making Businesses evolve rapidly. New systems are designed, redesigned and implemented, replaced and updated regularly. Different departments have different requirements and this usually leads to various information systems spread throughout the organisation. When it comes to making decisions, multiple departments are normally involved, bringing with them information from their own systems. As a decision maker, how can you efficiently and effectively get exactly what you need to make the right choice? The standard procedure may be to ask each departmental stakeholder to send to you the information that they deem relevant. Getting everybody into a room or a conference is hard enough without having to worry about missing information. Ultimately it leads to a string of meetings with various different bits of information that make little progress as data is missing, forgotten, misplaced or misrepresented.

A mi hijo icolás, que me ha dejado terminar este trabajo a pesar de robarle su tiempo de juego conmigo Y muy en especial, a Susana, mi fiel y leal compañera, y la luz que ilumina mi camino Agradecimientos En primer lugar, me gustaría agradecer a toda mi familia la comprensión y confianza que me han dado, una vez más, para poder concluir definitivamente esta etapa de mi vida. Sin su apoyo, no lo hubiera hecho. En segundo lugar, quiero agradecer a mis amigos Rafa y Carmen, su interés e insistencia para que llegara este momento. Por sus consejos y por su amistad, les debo mi gratitud. Por otra parte, quiero agradecer a mis compañeros asesores militares de Nextel Engineering sus explicaciones y sabios consejos, que sin duda han sido muy oportunos para escribir el capítulo cuarto de este trabajo. Del mismo modo, agradecer a Pepe Hevia, arquitecto de software de Alhambra Eidos, los buenos ratos compartidos alrrededor de nuestros viejos proyectos sobre XMPP y que encendieron prodigiosamente la mecha de este proyecto. A Jaime y a Bernardo, del Ministerio de Defensa, por haberme hecho descubrir las bondades de XMPP.

  • Openfire Service Level Agreement
    Service Level Agreement Technical Services — Communications Service University Technology Services 1. Overview This Service Level Agreement (SLA) is between University Technology Services (UTS) and either departments or groups choosing to utilize the internal Oakland University instant messaging (OUIM) service. The OUIM service is currently referenced by talk.oakland.edu and runs XMPP/Jabber software called Openfire. Under this SLA, UTS agrees to provide specific information technology (IT) services. This SLA also covers performance and reliability targets and objectives. Section 7 requires the signature and contact information of the group coordinator as an agreement to the SLA. OUIM is an online service that is available on campus and off campus. The requirements to utilize the service are a NetID, an XMPP client, and an Internet connection. XMPP clients are available online. The UTS Helpdesk supports the XMPP clients Spark, Pidgin, and Adium. Instructions are available on the UTS Web site at http://www.oakland.edu/?id=13849&sid=70. 2. Purpose The purpose of this SLA is to establish a cooperative partnership between UTS staff members with the community of customers who may opt into its use by clarifying roles, setting expectations, and providing service objectives and limitations. 3. Terms of Agreement This service is provided on an ongoing basis. From time to time, it may be reviewed and modified by UTS. Modifications to this agreement will be done at the sole discretion of UTS and the Technical Support and Services team (TSS). 4. Service Hours Regularly scheduled maintenance will be scheduled during low-use hours as much as possible; such work will be done either before 8:00 A.M.
