Final step of convergence: ALL IP

voip solutions The increasing convergence of voice and data has been going on for many years. The shift towards Voice over IP (VoIP) has already started!

In some countries such as Germany, there has been going on a discussion about when to decommission the public ISDN networks. The end of ISDN and analog telephone connections is approaching. In Germany all current landline connections will be shifted to IP based connections by the end of 2018. All data, whether voice, email or video, will be exclusively transmitted by the Internet Protocol IP.

Impacts

Having only one technology for all telecommunication networks requires some essential changes. Network providers take advantage from the benefit of a simpler and more cost-effective network structure. Numerous companies have enjoyed (and still do) the advantages of ISDN services, such as X.25, FTAM, CAPI or OFT. Nevertheless, let’s do not forget the most basical part of telephony which is without any doubt the voice quality. ISDN offers an excellent voice quality and of course no one who has already enjoyed a very high quality wants to move a step back. As a consequence the voice quality of VoIP has to be the same as of ISDN (at lease more or less) and a solution has to be found in order to ensure the quality.

Voice Quality – Quality of Service (QoS)

Quality of Service is the magic word and guarantees exceptional voice quality when you use Voice over IP technology. Professional routing solutions always provide QoS functionalities which give, for instance, voice traffic a higher priority for making sure that there is always sufficient bandwidth for voice applications. It classifies the streams of data and a sophisticated traffic management gives preference to voice data over e-mail data within a VPN tunnel. This results in exceptional voice quality even when bandwidth usage is at its highest. In order to provide maximum security, a professional integrated IPSec implementation uses preshared keys as well as certificates.

Conclusion

Voice quality is only one challenge to cope with when the final shift to ALL IP will happen but it is certainly one of the most fundamental requirements for anybody picking up the phone. The strict separation between the competence areas data and voice is history and ALL-IP will be no longer a vision of the future. In this current transition phase, it is absolutely necessary to have a strong partner with multidimensional know-how because ALL IP not only brings two worlds together but merges them. Teldat is in an excellent position because two of the manufacturer’s core competences are data and voice. Therefore Teldat is a strong partner to have when entering the new world of ALL IP.

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.
