CompanyFlex

To be able to use a cloud-based telephone system from Telekom flexibly and independently of location, even with multiple teams, choose one of our CompanyFlex Cloud PBX tariffs. Depending on DSL availability at your location, you can use between 16 and 1,000 Mbit/s.

With these tariffs, you can even integrate your employees' work smartphones as mobile extensions.

For an existing telephone system or a local telephone system in general, use our CompanyFlex SIP-Trunk tariffs. Depending on the available Telekom DSL speed at your location, you can select up to 1,000 Mbit/s for your business Internet connection.

SIP trunking is comparable to a telephone connection based on a data line. It allows multiple individual or extension numbers to be operated in IP-based telephone systems with just a single access account. You can connect a stationary telephone system via SIP trunking.
Cloud PBX consists of a connection for telephony and internet, a cloud telephone system with functions for audio and video conferencing and messaging (message and data exchange). The functions can be used independently of location with all IP-enabled end devices such as laptops, smartphones or tablets. With CompanyFlex, the cloud-based telephone system is always included – even if you initially decide to use a stationary telephone system via SIP trunking – the Cloud PBX can be easily activated yourself at any time.

You are familiar with individual telephone numbers from your private life; they are the part of the telephone number that follows the area code. In contrast, extension numbers consist of a so-called number block, which can be used to dial individual terminals of a telephone system directly. A number block consists of a series of consecutive numbers that are appended to a base number. The first digits after the area code (base number) are always the same, and additional digits – the extensions – can be used to reach individual employees, fax machines, conference rooms, etc.

You can find more information on this in our guide article. "Success factor: type of telephone number".

Both Cloud PBX and SIP Trunk offer professional services for those who do not want to take care of the setup or administration themselves. In addition to an on-site analysis, installation workshops, installation services and training courses can be booked as required to ensure smooth setup and use. About CompanyFlex Services
