In a business environment where efficiency, mobility, and cost reduction are key, IP telephony for companies stands out as a crucial solution for improving communications. This technology not only replaces traditional telephony, but also offers a new way to understand how a company can communicate with its clients, suppliers, and distributed teams.
At Inmove IT Solutions, we help SMEs adopt custom VoIP solutions that are secure, scalable, and easily integrated with their current systems—empowering them to take a major leap in corporate communication. In this article, you’ll discover why more and more businesses in Barcelona and across Spain are switching to VoIP—and how you can too.
What is VoIP Telephony and How Does It Work?
VoIP (Voice over IP) is a technology that enables telephone calls over the internet instead of using traditional phone networks. Instead of transmitting analogue signals, it converts voice into digital data that travels over the network just like any other information.
For companies, this means internal and external calls can be managed from any device with internet access, including IP phones, computers, or smartphones. Additionally, systems such as VoIP switchboards allow communications to be controlled and optimised from a single centralised platform.

VoIP vs. Traditional Telephony: Advantages for Your SME
Unlike conventional analogue lines, IP telephony offers numerous technical and economic benefits:
- Cost reduction: eliminates standard call charges, especially for international calls or between offices.
- Scalability: adding new lines is easy, with no need for physical wiring or installations.
- Mobility: employees can make and receive calls from anywhere with internet access.
- Advanced features: such as voicemail to email, call recording, video calls, or CRM integration.
Implementing VoIP doesn’t just modernise your infrastructure—it provides your business with a tool that boosts productivity and collaboration.
Key Benefits of IP Telephony for SMEs
Many SMEs still believe that VoIP solutions are only for large corporations—but that couldn’t be further from the truth. Here are some specific benefits for businesses with 10, 50, or 100 employees:
- Ongoing cost savings: reduced fixed costs and free internal calls.
- Professional image: features such as automated attendants or extension numbers enhance your business’s reputation.
- Centralised control: access call stats, recordings and user management from a web dashboard.
- Integration with business tools: from email to applications like Teams or Salesforce.

How to Implement VoIP in Your Business in 5 Steps
Migrating to VoIP may seem complex, but with the right guidance, it becomes a smooth, disruption-free process. At Inmove IT Solutions, we follow a five-step methodology:
- Needs assessment: we evaluate call volume, office locations, users, and current tools.
- Infrastructure selection: we determine whether to use an on-site, hosted, or hybrid switchboard (on-premise + cloud).
- Installation and setup: we configure routers, IP phones and networks to ensure voice quality.
- Training and support: we train your staff and provide ongoing assistance.
- Maintenance and scaling: updates, 24/7 support, and the option to expand functionality as needed.
VoIP and Remote Work: Enhancing Collaboration
The rise of remote working has increased the need for flexible solutions to keep dispersed teams connected. VoIP meets this challenge by allowing employees to work from home or on the move with the same capabilities they have at the office.
With tools such as softphones, mobile apps, or integration with videoconferencing platforms, IP telephony becomes a key ally for maintaining productivity, wherever your teams are located.
Save with VoIP: Strategies for Local Businesses
Local businesses—such as accountancies, clinics, law firms or shops—can gain tremendous benefits from switching to VoIP. Key strategies include:
- Replacing landlines with mobile VoIP extensions.
- Setting up automated business hours responses.
- Integrating the system with WhatsApp or email.
- Reducing fax use by centralising everything via business email.
A common case is companies with multiple locations that unify their call systems with IP telephony—cutting duplicate line costs and improving customer service.
VoIP Security: Protect Your Business Calls
One of the most common concerns around VoIP is security. Since it uses the internet as a communication channel, it’s essential to safeguard calls from interception or unauthorised access.
At Inmove IT Solutions, we implement security measures such as:
- Call encryption (SRTP/TLS).
- Secure authentication and suspicious activity blocking.
- VoIP-specific firewalls and network segmentation.
- Active monitoring and alerts for unusual activity.
