BYOD and Telephony: integrated solutions and security

The concept of bring your own device BYOD is a growing trend for business IT. There are a variety of benefits allowing users to supply their own PC and mobile devices.

Employees can easily check e-mails, manage appointments via social networks and search the web. Many companies offer their own apps to allow access to corporate data, enterprise applications and enterprise infrastructure.

All IP trend

At the same time the All IP technology trend with its increasing convergence of voice and data allows VoIP Service Providers to support telephony with standard LAN devices as long as it supports the Session Initiation Protocol (SIP). In this case BYOD, or bring your own device, is a service that providers offer, allowing users to configure any SIP based device.

There are also free mobile apps and with costs for iOS and Android that enable calls via Wi-Fi and 3G/4G using your VoIP provider.

So what could be more obvious than using a smart phone also as a mobile phone over the wireless LAN in the office. This way some business apps offer convenient telephony with a variety of service functions such as hold, toggling, call transfer and conference calls. Wi-Fi suitable infrastructures allow a high quality of telephony with seamless handover, over the entire wireless LAN. As a further benefit many users have realized that it is possible to have incoming and outgoing business calls at any location within a building offering a good and stable Internet connection.

Where there is light there is also shadow

Many, especially larger companies, have noticed security issues caused by BYOD. However, up to a certain point, they have found a solution thanks to security strategies, using so-called mobile device management (MDM), as well as using a comprehensive data-protection.

SMEs are less experienced in dealing with private IT. Many of the small and medium-sized enterprises don’t know yet how to handle this issue.

The use of VoIP causes particularly in the business sector further serious security problems by opening up the local network for all computers on the Internet. The result is that firewalls for SIP calls have to be opened and thus the use of Internet providers throws the door wide open to attacks from the Internet.

Teldat Solutions

This is where the experience of Teldat will come into complete effect. The solutions which Teldat offer the SME segment contain not only the infrastructure to integrate BYOD devices but allow also a secure integration of telephony. The hybird systems act as local SIP proxies. Hence, SIP apps can connect locally to the hybird systems without any risk. The hybird systems act as a session border controller and connect to the VoIP provider. BYOD devices can make phone calls using their SIP provider without being accessible for the provider or from the Internet .

If you use for example a smart phone outside the company, the key issue for mobile freedom is VoVPN, Voice over Virtual Private Network. The BYOD device establishes via an online Internet connection a secure connection to the office. In our example, the smart phone with VPN and all safety standards carries out all functions as if it were registered on the wireless LAN of the office. Furthermore, the telephone app acts as a normal extension. Outgoing calls display the central phone number of the office.

An involved supplier: The key to successful projects in XXI century

Soluciones teldatDue to the large number of technologies, the growing enterprise specialization and the vast amount of information available, XXI century projects are characterized by a high complexity level. It’s quite common to find projects that integrate multiple technologies which are initially unrelated, along with information processing systems in a changing and geographically wide environment.

New needs for project managers

In this century, project managers need to plan and design solutions that meets the customers’ needs with tight deadlines and budgets, as well as being able to adapt to contingency planning. They play a crucial role and are forced to quickly learn and understand many radically different technologies, in addition to being able to explore the market looking for available solutions, comparing and choosing the best suited to the requirements in terms of functionality and costs.

Given the wealth of information available and the high level of specialization within several markets and technologies, the technological suppliers often become the project manager’s best allies. The involvement of an experienced supplier in each of the project areas, incorporates the specific “know-how” to each of the mentioned project sections. This ensures good project design, planning and implementation and also increases the chance of success.

Involved suppliers: the key to success

An involved supplier that understands the project as a whole, will provide information on its product, technology or services from an expert’s point of view, allowing a more robust design which will integrate more easily with the other project’s components. During the planning stage, the forecasts related to the different project phases are crucial, and an involved supplier will provide reliable information to estimate timing, increasing the probability of fulfilling the foreseen tasks.

During the implementation phase, the project’s high complexity increases the likelihood of unforeseen issues. The management of contingencies is essential and the supplier’s degree of involvement within the project is crucial at this stage. Generally, having a large supplier with standardized products and little flexibility, implies that the project manager must assume most of the initiative and contribute him/herself the possible solutions and alternatives which will allow reaching the project objectives.

However, collaborating with suppliers who are used to evaluating their clients’ projects as their own, by providing own resources and venturing on the project’s success, facilitates the management of these contingencies. The supplier, as an expert in certain project sections, has the knowledge to analyze and study the possible technical contingencies, as well as accelerating the time in which they can be carried out, by changing its components and/or providing possible alternatives. In the management planning, an involved supplier will find ways to accelerate its processes to adjust itself as much as possible to planning changes that may have been put into place.

For example, an involved manufacturer would be one that, in addition to incorporating all the processes that optimize its devices’ quality and price, also introduces services into its added value chain. These facilitate their products development and can range from guarantees and maintenance to facilitate project management, to having consulting departments and technical advice centers, to accompany their client in the project’s first stages.

Teldat, with 30 years’ experience in projects, is a flexible company that has always been able to understand their customers, getting involved as a supplier, seeing their customer success as its own. That nature has been one of the founding points of a successful company developed around its customers, that has premise not only to provide innovative and quality technology, but also the whole project support, and ultimately the necessary involvement to ensure their customers’ project success.

…and a new year starts

teldat logoA year that has a very special meaning for Teldat, because during 2015 we will celebrate the thirtieth anniversary of our company’s establishment.

Thirty years in which we have been participants in the amazing technological evolution of communications, from the first modems to the latest 4G products. Thirty years that have led us from our very first small office (similar to some famous garage start-ups) to four continents, competing with global leaders. Thirty years that we have shared with our team, suppliers and customers, with whom we also hope to share the celebration of such a special birthday.

It will also be an important year because it’s the year in which we will see the successful accomplishment of many projects, investments and initiatives, which we have been working on during these last few years, and especially in 2014. Moreover, also because if the forecasts are reached, this year should be better than previous years. Not only for us, but for everyone and this will be very good news.

That’s why we commence 2015 with strength, enthusiasm and ambitiousness. In fact nothing very different from what we have always done at the beginning of each year, during the last thirty…


A Year ending…

Anna Maria Schmitz - Navidad 2014…which for Teldat has been an important and significant year, successful and with many new projects. A year of integration and growth.

This year 2014 that will finish shortly, has meant among other things, a change in the way Teldat has interacted with our customers, suppliers and all those interested in our technology and what we do.

Since June, when we launched this blog and our Twitter and LinkedIn accounts, we have shared many things with our readers: activities, knowledge, opinions, projects, case studies. Everything that we considered relevant to show what makes and what is a small Spanish multinational company which is able to compete with the largest companies within its market sector.

To end this year, we want to thank all our readers for their loyalty and interest as well as welcoming more than 1.000 new followers who have joined our communication channels.

Moreover, we especially want to wish all of them, to all who read us occasionally and all our customers and friends, to have a very merry Christmas and may 2015 be as fruitful for them as this 2014 has been for us.

What is a wireless LAN controller and who has taken it to the cloud?

colibri serviceThe main function of a traditional wireless LAN controller (WLC ) is to configure wireless access points (AP) that connect to it locally.

However, due to the technological characteristics of a wireless area network (or Wi-Fi as it is commonly known), the traditionally used Wi-Fi network architecture and the manufacturers’ commercial strategies, a WLC carries out or can carry out many other functions, which can be grouped into the following categories:
