Carrier Voice
Due to the changes which have taken place in the telecommunications services market, network operators find it increasingly difficult to differentiate themselves through the provision of connections or broadband. Furthermore, increasing competition leads to ever lower revenues from traditional telecommunications services. But it is not just traditional telcos that have to face these challenges. Increasingly, they also affect companies which, as internet service providers, develop and sell IP-based value-added services.
While the telcos have to make sure that their TDM-based infrastructures will be able to handle IP, more and more internet service providers are looking at offering scalable voice services based on VoIP (Voice over IP) on top of their established IP value-added services such as VPNs or internet access. In both cases the contents as well as the switching of phone calls and multimedia services will not be bound to certain channels and transported across a special synchronous network but will be seen as an application on a suitable IP network.
The fact that current IP networks can work in real time means that they cannot just handle traditional services such as telephony and video transfer but also new services such as presence, hosted IP services, geographically unrestricted telephony with only one number as well as IP-TV. This does not just allow the exploitation of synergies. The openness of the interfaces gives the necessary flexibility to quickly supplement and swap new services.
Our experts here at Xantaro have been following these developments for some time. Looking at the current technology and design transition from traditional voice networks to an IMS (IP Multimedia Subsystem, 3GPP) and NGN (Next Generation Network, ITU-T) based network structure and the carrier and service provider market in particular, they place special emphasis on stability, compliance and the fact that new technologies should be future-proof.
Thanks to its know-how in the areas of transport, access, IP and telecommunications services and thanks to its efforts to achieve standardization in the SIP environment Xantaro has a good overview of the requirements of current and future networks. Thanks to a careful choice of IMS, NGN and SIP partners in the areas of
- softswitch
- media gateways
- session border controller
- IP-PBX, IAD, set-top boxes, IP-phones
- application servers for presence, IP-centrex
- mobile core network functionality
the company is able to offer a complete solution as well as a “construction kit” for new services.
In spite of the complexity of the various components and protocols Xantaro always focuses on the “end-to-end” view. This is why Xantaro supports customers as early as during the evaluation phase. The IMS/NGN solutions developed and tested by Xantaro will function with maximum reliability, both before and during implementation in your production environment. Make use of Xantaro expertise for the development and successful implementation of innovative telecommunications services.
