In this era of advanced IP, the transmission of speech no longer requires any special hardware. It runs as a VoIP application on servers and communicates over data networks. Companies should therefore centralize their typically decentralized aged-ISDN. This brings costs down and increases security and call quality simultaneously. T-Systems offers SIP trunking and SIP gateways based on the relevant session initiation protocol.
Operational management used to be very strenuous. In the time of ISDN, there was a telephone system at almost every company. This made operation costs correspondingly expensive. The IT department had to maintain each telephone system individually, book individual new ISDN connections for each location, and install them – a difficult protocol for any IT employee to handle. SIP trunking and gateways weren't yet considered for use in connection with landline calls.
Classic phone call systems, much like the internet, are a core functionality in any company. Tele- and web conferences are becoming increasingly popular. However, companies invest comparatively little in their telephone infrastructure. Established technologies are now well developed and reliable. They may not appear essential for the communication processes of a company since a telephone conversation is self-explanatory. But the configuration, functionality, and reliability of the technology behind it are becoming increasingly decisive for many business processes crucial to a company's success.
The switch from traditional telephone systems to IP systems now offers companies the best opportunity to optimize their network design and to centralize with Voice over IP. Calls no longer require any special hardware with advanced IP. Like email, it runs as an application on servers and communicates over data networks. And it is almost irrelevant now where the server is located. Phone calls via VoIP have never been easier.
The technology change can have an impact on internal organization. The specific purchase of a telephone system or a specific form of call service management will soon be a thing of the past. Calls will simply be more like one application within a broad range of IP-based services.
SIP trunks and SIP gateways from T-Systems are the VoIP successors of ISDN and analog connections. SIP (session initiation protocol) is a protocol that allows IP-based communication platforms to connect with public telephone networks, for example. Therefore, SIP improves the overall telecommunication infrastructure of a company.
Both telephone technologies follow different approaches to finding solutions. Standardized SIP trunks are mostly used locally. They replace traditional telephone connections. SIP trunking requires no new cable to be set up. Companies book various additional voice channels and only pay for the required amount.
