VoIP Application Interface Layer VAIL is the core of the Windows CE VoIP solution. It includes various components that OEMs can use to quickly build customized VoIP devices. Service providers and enterprises can use VAIL to develop value-added services and deploy them to users.
Similar to the sample TUI application, Microsoft provides VAIL in source code. OEMs, service providers, and enterprises can modify VAIL or replace it with a different solution. VAIL consists of the key components listed in the following table.
In the Windows CE VAIL solution, the configuration data store provisions the phone through Extensible Markup Language (XML) or Lightweight Directory Access Protocol (LDAP) by providing the phone's SIP settings, dial plan, and associated servers.
VoIP Manager and Current Call Objects control active calls and call control, such as hold, forward, redirection, conferencing, and SIP registration.
VoIP applications that support teleworkers IP telephony is extending new features and capabilities to mobile employees and road warriors, and revolutionizing the way teleworkers connect and work with their counterparts back in the
office. In this test we compared the telework offerings of five leading IP telephony vendors under real-world IP WAN conditions. We found that the vendor packages - from Alcatel, Avaya, Cisco, Mitel Networks and Nortel - vary in their security infrastructure; recommended equipment; breadth of new applications and features; price; and quality of voice
communications. We defined our review criteria in four general areas.
? Telephony features and collaboration features.
? Hard phone and soft phone performance.
? Configuration, integration of components, setup and monitoring of teleworker connections.
? Security provisions for protecting the teleworker's IP connections.

VOIP Application Numerous VoIP Applications are in use today differing in exact scope and nature of your requirements. New VoIP Application deployments for VoIP networks can use a variety of network protocols and architectures. Let?s discuss some of them.
Today?s Advanced Intelligent Network (AIN) provides many useful features common to callers today. These features include Caller ID, Voice Mail, Call Waiting, Pre-and-post paid calling cards, 911, Call Blocking, and Auto Call-back to name a few. These VoIP Application and features represent years of development and investment by vendors and service providers, and are delivered via a proven circuit switched infrastructure.
Advanced VoIP Application: The migration to VoIP networks is being driven by a number of factors; the key concept is that of advanced services.
The IP interfaces of these devices can provide the telephony signaling as
well as the media interfaces. This provides for simpler distributed
signaling and processing capability reduces the cost of components, and
speeds up application development and deployment. The new IP based
application or VoIP Application can be delivered in a variety of methods
depending upon their complexity.
VoipCenter SIP Application Server Software The VoipCenter SIP Application Server software is built on Voxeos proven Call Control XML (CCXML) engine and has routed over one billion calls since its first production deployment in early 2002. CCXML lets any company create intelligent, dynamic SIP applications that can screen, route, transfer, and initiate SIP VOIP calls-including SIP redirect, proxy, and Back-to-Back User Agent (B2BUA)
applications. The VoipCenter SIP Application Server also supports least-cost and multi-network call routing with the ENUM route directory standard.
CCXML is the call control application standard from the World Wide Web Consortium (W3C), the same standards body that delivered HTTP and HTML -- arguably the two most successful applicaton development standards ever created. CCXML gives VOIP developers total control over how phone calls are placed, answered, transfered, conferenced, routed, and more. CCXML works hand-in-hand with any web application server or platform to enable dynamic, intelligent control over all VOIP calls.
Samsung Introduces Mobile VoIP Application Samsung has introduced its latest enterprise-level wireless application, called OfficeServ Wireless, which is designed to transfer voice data over a wireless VoIP connection.
The new application consists of several primary components, including a wireless access point, a wireless interface card, and an interface for administration. It operates wireless on a 2.4-GHz frequency, and can support as many as 240 wireless handsets at any given time. Programming of the application can be done easily using a Samsung phone platform or a connected computer.
VOIP Applications Software Introduction The new concept in this case is the one behind VOIP (voice over IP)
the separation of services and infrastructure. It enables telecom operators to roll out new services over IP infrastructure by simply loading software onto servers?a process that's so easy and inexpensive that operators can experiment with services to find the most profitable
ones. Light Reading's directory, launched in this "Who Makes What" report, aims to encourage this development, by helping telecom operators and enterprises find the right software to furnish different VOIP services, such as multimedia conferencing, hosted PBX and centrex, SIP-based messaging, and contact centers.
The project has the support of a heavyweight backer ? the foremost VOIP industry association, the International Packet Communications Consortium (IPCC), which has endorsed Light Reading's initiative and is encouraging its members to participate in it

Performance at the VoIP Application Layer Securing IT networks is a serious and risky business. And the stakes are raised even higher when it comes to securing VoIP networks at the application layer. There is no all-in-one security solution for the abundance of VoIP and multimedia applications now available over packet networks, and IT managers must carefully evaluate their existing solutions and wade through the vast number of new solutions available to determine what is appropriate for their own networks.
IT security platforms built to protect against network-level and Web-based attacks are not designed to handle security issues at the application layer. VoIP-specific security attacks can allow unauthorized packets to run over a network, degrading performance, and can even intentionally flood a call server with requests, causing major service degradation. Standard firewalls and NAT solutions are not built to handle the upper layers of the network, and security solutions specifically designed to work with VoIP applications become necessary to maintain quality of service (QoS) within the network.
BroadWorks VoIP Application Platform Delivers BroadSoft, Inc., the leading provider of VoIP application software, today announced that Telefónica de España has deployed VoIP services based on the BroadWorks VoIP application platform. The service, deployed over the Ericsson infrastructure, is one of the first IMS deployments delivering VoIP services to the residential and SME markets.
Telefonica is using value-adding BroadWorks applications based on an IMS-ready platform to deliver primary line services to residential consumers and SMEs over any broadband connection. Using the BroadWorks platform, Telefónica customers are able to manage their own service preferences via the Web. Premium applications such as simultaneous ring, where any call to the home number will automatically ring any other number specified by the user, can be managed directly by the customer, empowering end users to make their own service changes such as setting up voicemail preferences and call forwarding.
