What is VoIP and how does it work in businesses?

VoIP (Voice over Internet Protocol) no longer transmits voice signals via the traditional telephone network, but via the Internet. This involves the use of IP telephones, VoIP gateways, or software solutions.

  • Connection via LAN or WLAN
  • Use of existing Internet infrastructure
  • Integration into existing networks and systems

VoIP not only enables telephone calls, but also offers comprehensive functions such as call forwarding, group calls, and conference calls.

What are the advantages of VoIP telephony?

Choose proven VoIP telephony for your company for the following reasons:

  • Location-independent accessibility
  • Scalability without expensive hardware upgrades
  • Central management via web portals
  • Cost savings compared to traditional landline telephony
  • Compatibility with UC solutions (Unified Communications)

Which VoIP solutions make sense for businesses?

Businesses can choose between different types of VoIP systems:

  • IP telephone system: Local, hardware-based solution in your own server room
  • Virtual telephone system (cloud PBX): Cloud-based solution, fully manageable online
  • SIP telephone system: Enables communication via SIP trunks with a high degree of flexibility

For small and medium-sized businesses (SMBs), a VoIP telephone system for SMBs or a virtual telephone system is often ideal – low investment costs, easy scaling, and high mobility.

The following hardware is relevant when introducing VoIP:

  • IP telephones: wired or Wi-Fi-enabled
  • VoIP gateways: Integrate analog devices or ISDN systems into IP telephony
  • SIP phones: Compatible with almost all common VoIP services
  • VoIP conference phones: For professional meetings with multiple participants

When purchasing an IP phone, make sure it is compatible with your VoIP or SIP telephone system. Snom and Avaya in particular offer certified devices for many systems.

How can companies successfully switch to VoIP?

  1. Analyse requirements: Number of users, locations, desired functions
  2. Select a VoIP provider: Consider support, rates, and integrations
  3. Define the telephone system: Local or virtual?
  4. Procure end devices: Purchase suitable VoIP phones, optionally with headsets
  5. Check the network: Sufficient bandwidth, stable internet connection
