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.

Convergence: Integral solutions for routers and professional telephony

Teldat hybrid solutionsThe increasing interconnectedness between the fields of information technology and telecommunications is not new. We all know that these two worlds have grown more and more together and still do (keyword: convergence). On the one hand business communication requires professional telephony and professional routing, but on the other hand, no company, especially in the SME segment, wants to buy only a PBX in order to fulfill their telecommunication needs and no company acquires a router, and let it be as professional as possible, only for routing. The SME segment wants one device for both needs. They are driven by costs but at the same time, they want all professional benefits like larger companies as well.

Besides costs and efforts, deep integration into their technical environment and into their workflows is a must. Standardized interfaces in applications and devices, sometimes even certified by third-party suppliers, are the fundamental requirements for a seamless integration. Further challenges, such as usability, flexibility, security of investment, mobility and as a matter of course security have to be guaranteed at any time. Particularly mobility has stressed the requirement of security lately. Over the last few years the number of private smart phones and tablet PCs has continuously increased and many of these users also take advantage of their devices for business purposes (key word: BYOD or bring your own device). The convenience of eliminating the difference between “in the office” and “on the road” changes daily business while availability and communication use remain unaffected. This balancing act between mobility and security is certainly one of the biggest challenges.

Besides various challenges mentioned above which we have to overcome in the SME segment, we come to the conclusion that it is essential to have some kind of “PBX with business routing” or a sort of “router with professional telephony” for SMEs. It is necessary to find a solution that can cope with telecommunications as well as with information technology in order to fulfill all business needs for SMEs. From the perspective of the customer the crucial question that he asks himself is: What kind of device would be the professional solution? And who is able to really offer both? An IT company selling routers with telephony? Or a telecommunications company offering PBXs with professional routing? Isn’t there a real ICT company which offers both? As a matter of fact, there is. Teldat. Possibly the largest European manufacturer of ICT devices for the business market, offers true convergence. Its Bintec brand stands for professional routing and its Elmeg brand for professional telecommunications solutions. The Elmeg hybird 120 and 130 is the true converged solution to meet all communication demands of SMEs and even freelancers and home offices.
