Corporate Voice
Next-generation communication

The public switched telephone network (PSTN) remains the backbone of voice communication for many companies – but it often struggles to keep pace with a changing business world.
Übersicht
T-Systems Corporate Voice Solutions (CVS) offer a way forward: a single customer-specific contract for PSTN lines and connection charges, plus optional network-based, value-added modules such as a central switchboard, a single contact number, audio and data conferencing, and a virtual private network across multiple offices. It is possible to integrate existing PBXs, home offices, and cell phones and smartphones. Mobile and remote workers are connected to the main telephone infrastructure - so they can be reached via their office extension, and have access to conferencing, forwarding, and other functions.

Improve customer service, simplify accounting processes

The CVS Service Telephony module offers the option of toll free (e.g. 0800 in Germany) or shared cost (e.g. 0180) numbers to businesses with significant customer call volume. Moreover, CVS simplifies accounting, merging invoice data from multiple voice and data contracts if required, and enabling electronic allocation of charges to customer-specific cost centers.

SIP trunking – your path to VoIP

VoIP platforms are fast overtaking PSTN systems. By leveraging VoIP technology, you can centralize PBXs and use new services such as UCC. What’s more, you cut costs by replacing multiple, distributed analogue or ISDN telephone lines with a single, central SIP trunk. A phased migration is the ideal path to IP communication: T-Systems deploys SIP trunking to connect IP telephone systems to the conventional public telephone network.
