Renewal of the Active Network Infrastructure
As part of this project, the existing active network infrastructure was modernized and made fit for the future. The goal was to introduce a powerful, secure and scalable network and WLAN infrastructure, including a Network Access Control (NAC) solution to improve network security and centralized access control.
At the beginning of the project, a comprehensive requirements analysis was carried out, taking into account the technical, operational and security-related requirements of the hospital sites. On this basis, a technical tender was prepared for new switches, WLAN access points and the NAC solution.
The successful implementation of the project established a modern, standardized and secure network infrastructure that meets the growing requirements for availability, mobility and IT security in hospital operations.
Activities:
- Supporting the tender process, including technical evaluation of offers and bidder evaluation
- Leading and managing the entire project implementation
- Coordinating the project process with internal stakeholders, business units and hospital IT

About the technology
Voice over IP foundations
VoIP, or Voice over IP, carries voice calls through IP networks instead of traditional telephone lines. Companies use it for business phone systems, softphones, video calling, contact centres and unified communications. A sound implementation covers call quality, availability, security and a clear plan for managing users and numbers.
Systems and use cases
- SIP trunking and hosted business telephony
- Call queues, IVR menus, recording and voicemail
- Contact centres with routing, monitoring and reporting
- CRM-connected calling and click-to-dial workflows
- Office, remote and mobile communication setups
VoIP can support a small distributed team or a complex service operation. The right design depends on call volume, user locations, existing network capacity and the level of control the company needs.
Protocols and tooling
SIP is central to many VoIP deployments, while RTP transports audio and related media. Specialists work with PBX systems such as Asterisk, FreeSWITCH and 3CX, as well as cloud services, SBCs, desk phones and softphone applications. They also configure DNS, firewalls, VLANs, QoS and identity controls.
When expertise matters
Companies often bring in freelance expertise during a telephony migration, merger, office rollout or contact-centre redesign. It is also valuable when calls suffer from jitter, latency, dropped sessions or one-way audio. In Germany, professionals may need to coordinate remote delivery with on-site network, handset or carrier work across several locations.
Delivery and integration
A strong specialist maps call flows, numbering, users and permissions before changing production systems. They connect VoIP with CRM, helpdesk, Microsoft Teams or other collaboration tools without weakening security or reporting. Good documentation covers provisioning, emergency call procedures, failover, monitoring and handover to internal teams.
Quality signals
Look for professionals who can explain codec choices, SIP registration, NAT traversal and network priorities in practical terms. They should test voice quality under realistic load, isolate problems across the LAN, WAN and carrier, and define recovery steps. Clear communication in German or English can make remote collaboration with teams in Germany far more effective.
Frequently asked questions
Need clarity? These are the questions we hear most often about VoIP.
Companies use VoIP for business calling, internal extensions, contact centres, softphones, call queues and CRM-connected workflows. It can also support remote teams, mobile users and video-based collaboration through a shared communications setup.
Voice over IP usually offers more flexible user management, software integrations and location independence than traditional on-premise phone systems. Traditional telephony may still suit environments with strict legacy requirements, limited network capacity or a strong preference for dedicated infrastructure.
A strong VoIP professional should understand SIP, RTP, firewalls, NAT, DNS, VLANs and quality-of-service controls. Experience with Asterisk, FreeSWITCH, 3CX, SBCs, CRM integrations and carrier coordination is also useful.
The right level depends on the scope, not simply on the technology label. A basic softphone rollout may need focused configuration skills, while a multi-site migration requires proven capability in call flows, number porting, security, testing and failover.
Yes, much of VoIP configuration, testing and monitoring can be completed remotely. On-site support may still be needed for cabling, handsets, local network changes or carrier equipment, so agree early on which tasks require physical access and whether German-language communication is expected.
Common causes include congestion, unstable Wi-Fi, incorrect QoS settings, high latency, jitter, packet loss and faulty NAT or firewall rules. A capable specialist measures the network and call path instead of changing codecs or hardware without evidence.
Ask for examples of comparable telephony environments and request a clear approach to discovery, testing, security and handover. A reliable VoIP specialist explains trade-offs plainly, documents call flows and can show how incidents will be monitored and resolved.
Clarify the current PBX or cloud service, carrier, numbering plan, network ownership, integrations, security rules and access to test users. For IP telephony work in Germany, also confirm remote or on-site expectations, language needs, maintenance windows and responsibility for physical equipment.
