Renewal of the active network infrastructure
As part of this project, the existing active network infrastructure was modernized and aligned for the future. The goal was to introduce a high-performance, secure, and scalable network and WLAN infrastructure, including a Network Access Control (NAC) solution to improve network security and central access control.
At the start of the project, a comprehensive requirements analysis was carried out, taking into account the technical, operational, and security-related needs of the clinic sites. Based on this, a technical tender was prepared for new switches, WLAN access points, and the NAC solution.
By successfully delivering the project, a modern, standardized, and secure network infrastructure was established that meets the growing demands for availability, mobility, and IT security in clinical operations.
Tasks:
- Support of the tender process, including technical evaluation of the offers and bidder assessment
- Lead and coordinate the entire project delivery
- Align the project process with internal stakeholders, business units, and the hospital IT team
- Manage external service providers during implementation and installation of the systems
- Monitor implementation, including quality control, project acceptance, and issue management
- Coordinate communication between hospital IT and external service providers during the NAC implementation
- Carry out escalation management for technical and organizational challenges

About the technology
What VoIP does
VoIP, short for Voice over Internet Protocol, carries voice calls through IP networks instead of traditional telephone lines. Companies use it for business telephony, softphones, video-enabled communication, internal extensions and customer contact services. It can support office, mobile and remote communication through one connected system.
Core components
A reliable VoIP environment combines SIP trunks, IP phones, session border controllers and call-management software. Specialists work with hosted and self-managed architectures, cloud voice services, network quality controls and identity or access systems. They also handle codecs, call routing, number porting, recording and failover planning.
- SIP registration and trunk configuration
- Interactive voice response and call queues
- CRM, helpdesk and Microsoft Teams integrations
- Monitoring, quality analysis and troubleshooting
Where companies use it
VoIP supports sales teams, service desks, healthcare organizations, logistics operations and distributed offices. Common deliverables include a new phone system, a contact center migration, a remote-work rollout or an integration that connects calls with customer records. In Germany, projects may involve teams across several sites and collaboration between local staff and remote specialists.
When to bring in expertise
Freelance professionals are useful when call quality is inconsistent, a legacy PBX is limiting growth or a company is moving to a hosted system. They can assess network readiness, define the target architecture, compare service options and manage a controlled migration. Bring them in early when number portability, security, compliance or business continuity could affect the plan.
- A company is replacing an on-premises PBX
- A contact center needs smarter routing or reporting
- Remote teams need secure, reliable voice access
- Calls must be linked to CRM or service workflows
Skills that matter
Strong VoIP professionals understand SIP signaling, RTP media flows, DNS, firewalls, VLANs and network prioritization. They can work with platforms such as Asterisk, FreePBX, 3CX, Kamailio and major cloud communication services. Their wider skills may include Linux, APIs, identity management, automation, monitoring and contact-center operations.
How quality is judged
Good work starts with clear call flows, documented dependencies and tests for voice quality under realistic network conditions. Experienced specialists separate signaling problems from media, routing or device issues and explain trade-offs in plain language. They leave behind secure configurations, rollback plans, useful documentation and monitoring that an internal team can operate.
Frequently asked questions
Need clarity? These are the questions we hear most often about VoIP.
VoIP is used for business calls, softphones, call queues, contact centers, conference calls and integrations with CRM or helpdesk systems. It can connect office phones, mobile users and remote teams through a shared communication setup.
Voice over Internet Protocol uses IP networks rather than dedicated telephone lines, which can make routing, scaling and software integration more flexible. The right choice still depends on network quality, service availability, security requirements and the need to retain existing phone infrastructure.
A strong VoIP professional should understand SIP, RTP, firewalls, DNS, VLANs and network prioritization. Experience with Linux, APIs, CRM integration, identity systems, monitoring and contact-center workflows is also valuable.
The required depth depends on the scope, from configuring a small hosted phone system to migrating a multi-site contact center. For complex work, choose a VoIP specialist who can show practical experience with architecture, testing, security, number porting and recovery planning.
IP telephony can support remote and hybrid teams when users have suitable devices, stable connectivity and secure access. A specialist working with teams in Germany should also be comfortable coordinating across sites, documenting changes clearly and communicating in the language the project requires.
VoIP work can often be completed remotely through secure access, configuration tools and structured testing. On-site support may help with cabling, handset deployment, local network checks or a migration that must happen alongside physical phone equipment.
Ask how the VoIP professional approaches discovery, network assessment, call-flow design, security and migration risk. Request examples of documentation and testing, not only a list of platforms, and confirm that they can explain technical decisions to business and IT stakeholders.
High-quality VoIP work delivers clear call flows, stable media, secure signaling and predictable behavior during faults or network changes. The specialist should provide monitoring, test results, rollback options and documentation that lets the company maintain the system after handover.
The average hourly rate of freelancers in Germany who have used VoIP in their recent projects is 106 €, which corresponds to a daily rate of about 846 € based on an 8-hour working day.
