VoIP allows users to make voice calls over the internet instead of traditional phone lines. It works by converting voice into digital signals sent over broadband internet and converting back to regular calls. Key requirements are a broadband internet connection and computer/phone with VOIP software or adapter. VOIP has benefits like lower costs for consumers and businesses. While VOIP is banned for regular calls in Afghanistan, PC-to-PC VOIP like Skype is allowed. VOIP capabilities are widespread in applications like Windows Messenger, Xbox Live, and Skype.

VoIP (Voice over Internet Protocol) transmits voice and multimedia content over an internet connection. VoIP allows users to make voice calls from a computer, smartphone, other mobile devices, special VoIP phones and WebRTC-enabled browsers. VoIP is a valuable technology for consumers and businesses, as it typically includes additional features that can't be found on standard phone services. These features include call recording, custom caller ID, and voicemail to e-mail. It is also helpful to organizations as a way to unify communications.
The process works similarly to a regular phone, but VoIP uses an internet connection instead of a telephone company's wiring. VoIP is enabled by a group of technologies and methodologies to deliver voice communications over the internet, including enterprise local area networks or wide area networks.
A VoIP service will convert a user's voice from audio signals to digital data and then send that data through the internet. If another user calls from a regular phone number, the signal is converted back to a telephone signal before reaching that user.
VoIP can also route incoming and outgoing calls through existing telephone networks. However, some VoIP services may only work over a computer or VoIP phone.

Questions for VoIP Installers
What Is a VOIP Telephone?
A VoIP telephone is a VoIP (Voice over IP) phone that uses an internet connection to place and receive calls, rather than using a traditional telephone line. VoIP phones are becoming increasingly popular, as they offer a number of advantages over traditional landline phones. These phones can be used with any broadband internet connection, making them very versatile. VoIP phones also offer a number of features that are not available with traditional landline phones. For instance, caller ID, call waiting, voicemail, and three-way calling. VoIP phones are also generally less expensive than traditional landline phones. Our VOIP Installers here at NM Cabling are here to guide you through the design, installation and after care of your system.

Can I Use VoIP on My Network
Can my internet handle VoIP?
The Voice over Internet Protocol technology, as we know, allows users to make calls over the existing internet network or infrastructure. So how do we ascertain whether the networks available in our place will be able to support VoIP services? Also, what could be the requirements for the installation of a VoIP system? And what are the benefits and costs of VoIP? Let’s take a look at some of the key points that should be considered for VoIP to function on a particular network.
Requirements for VoIP
Network Internet Connection
As we know that VoIP functions in conjunction with the internet so it is one of the main prerequisites for establishing VoIP communication. The options available include both wired internet infrastructure based on broadband services and wireless internet such as Wi-Fi modems. Both systems utilize their specific hardware to establish VoIP services. In the case of wired broadband services, Ethernet cables and VoIP gateway can be used. On the other hand, the wireless network utilizes wireless internet modems in addition to Ethernet cables and VoIP gateways.
Network Bandwidth
Once the network is enabled with the internet, an analysis shall be conducted about the number of VoIP devices that are needed to be integrated into the system. The increase in the number of devices may slow down the network and cause problems such as network congestion especially if the bandwidth of the internet connection is low. Therefore, it is necessary to evaluate the network bandwidth to allow for a specific spare percentage of the bandwidth so that the devices can function properly. It is recommended to use 0.1 Mbps of bandwidth for every device/phone.
VoIP Service Provider
For a VoIP system to work a VoIP service provider has to be selected. Communication between VoIP phones or devices is made possible through the connection provided by the VoIP service provider as they allocate numbers and allow you to make calls to each other’s devices.

Voice over Internet Protocol with Novel Applicationsirjes
Internet Telephony, often denoted as Voice-over-Internet-Protocol (VoIP), has gained more and
more attention world-wide during the last decades. Voice over Internet Protocol (VoIP) technology has become
a communication alternative with the continuous increasing of Internet bandwidth and rapid advancement of
peer-to-peer (P2P) applications.In this paper three types of VOIP are explained: (i) PC to PC : this is the easiest
way to use VOIP, which enables you to talk and communicate Voice over Internet with all people over the
world. (ii) PC to Phone: which need a gateway that connects IP Network to phone Network. Its uses a device
called an ATA (Analogue Telephone Adaptor).The ATA allows you to connect a standard phone to your
computer or your Internet connection for use with VOIP. The ATA is an analogue to digital converter. (iii)
Phone to Phone: Where you need more gateways that connect IP network to phone networks, more phone
networks that connect Telephone set to gateway, and IP network that connect gateway to gateway. This paper
also explains Internet Protocol (IP) that VOIP uses to transmit voice as packets over an IP network as follows:
H.323 Protocols that provides the technical requirements for voice communication over LANs, while assuming
that Quality of Service isn't provided by LANs. Session Initiation Protocol (SIP) standard which is the standard
for establishing VOIP connections. This paper also explores Voice XML which is a markup language derived
from XML for writing telephone-based speech applications.In this paper also VoiceXML developed
environments(Gateways) are explained, where a list of all VoiceXML developers is included, and the most
popular VoiceXML development environments (Gateways) are explained in details.Finally, in this paper ten

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Introduction to Voice over
Internet Protocol (VoIP)
2. Voice over Internet Protocol (VoIP)
Voice over Internet Protocol (VoIP), is a technology
that allows you to make voice calls using a broadband
Internet connection instead of a regular (or analog)
phone line. Some VoIP services may only allow you to
call other people using the same service, but others
may allow you to call anyone who has a telephone
number - including local, long distance, mobile, and
international numbers. Also, while some VoIP services
only work over your computer or a special VoIP phone,
other services allow you to use a traditional phone
connected to a VoIP adapter.
3. ITU Definition for VoIP
Voice over Internet Protocol (VoIP) is referred to as
and broadly includes Voice over Broadband
(VoB),Voice over Digital Subscriber Line (DSL),
Voice over Internet (VoI), Voice over Wireless Local
Area, Network and Internet telephony.
4. How VoIP / Internet Voice Works
VoIP services convert your voice into a digital
signal that travels over the Internet. If you are
calling a regular phone number, the signal is
converted to a regular telephone signal before it
reaches the destination. VoIP can allow you to
make a call directly from a computer, a special
VoIP phone, or a traditional phone connected to a
special adapter. In addition, wireless "hot spots"
in locations such as airports, parks, and cafes
allow you to connect to the Internet and may
enable you to use VoIP service wirelessly.
5. Which Equipments are needed?
A broadband (high speed Internet) connection is
required. This can be through a cable modem, or high
speed services such as DSL or a local area network. A
computer, adaptor, or specialized phone is
required. Some VoIP services only work over your
computer or a special VoIP phone, while other services
allow you to use a traditional phone connected to a VoIP
adapter. If you use your computer, you will need some
software and an inexpensive microphone. Special VoIP
phones plug directly into your broadband connection and
operate largely like a traditional telephone. If you use a
telephone with a VoIP adapter, you'll be able to dial just
as you always have, and the service provider may also
provide a dial tone.
6. VoIP strengthen factors
For businesses: Security at a lower cost
For consumers: Significantly lower costs
For service providers: Lower investment, capital
and operating costs for operators, it can be
through :
Reductions in the bandwidth required to send any given voice
message; and
Economies of scale;
The possibility of converged services running over one network (as
opposed to multiple, older legacy networks).
Also it can be Enhanced innovation, New
business models and Entry into new markets for
service providers.
18. VoIP in Afghanistan
(13) Item of ISP License:
13.1 Voice over IP (VoIP) is not allowed under this
license agreement.
13.2 In order to comply with this clause 13.1 the
licensee must block all telephony and voice routing
ports and web sites as required by subsection 13.1.
19. Allowed VoIP in Afghanistan

Any voice communication from computer to
computer, commonly referred to as “PC to PC”,
including voice communication functions of
NetMeeting, ICQ, MS Messenger and other
programs as notified to the Licensee by the ATRA in
writing from time to time.
20. Concluding Thoughts
VoIP is one of many higher-level communications
capabilities among devices connected to the Internet.
VoIP is not an application.
VoIP is a capability that is part of many applications.
VoIP capabilities are already pervasive.
