Hosted PBX

Hosted PBX – Easy to integrate in any network

or – the modern solution for your company telephony

This solution combines the highest level of reliability with easy applicability. Starting with the first extension, the user has access to the entire scope of services offered by a fully-functional TC system.

With IP telephony using hosted PBX, the SIP end devices (table-top telephones) connect to the central telephone system on the network and can thus communicate with other end devices via data lines – and into all other networks.

Switching to Centrex-based VoIP telephone systems is recommended due to the reliable operation in redundant, high-security computing centers, the flexible scalability of the extensions and the buy&bill principle. Your company only pays for the services it actually uses. There is no more complex hardware that has to be specially managed. With a lifetime upgrade guarantee, no further costs are incurred for modernization in contrast to classical TC systems.

The switch to a hosted PBX is simple and fast. We completely set up the system ahead of time in cooperation with your company. From the time the system goes live, you can start making calls.

The preliminary consultation ahead of time is particularly important. We clarify, with your cooperation, which functions and features of the hosted PBX are relevant for your company and draft a plan on that basis.

The set-up and installation of the VoIP telephone system is handled by our competent team consisting of trained technicians. Of course our support is available afterward if you have questions or want to make changes or if you have additional requests.

IP telephony as a virtual telephone system – it’s that easy

The SIP end devices connect to the central telephone system on the network and transmit voice packets to other end devices via data lines. The signalizing data is encrypted using the G711 codec which optimizes both the voice quality and the bandwidth requirement (TÜV-certified). Additional security is provided by voice data encryption using SRTP feature.

Fax transmissions from conventional end devices can also be integrated into the system via the T38 protocol. A so-called ATA (Analog Terminal Adapter) converts the analog signal into a digital signal and can thus communicate with the hosted PBX system. You also have the option of completely switching to eFax. With this solution, faxes can be sent directly from any office application. Faxes are received directly as a PDF attachment in your personal email inbox.
