Benefits Of VoIP Over Traditional Landline
More and more businesses are quickly moving to VoIP, and there’s an excellent reason for that. Below are the major benefits that make VoIP better than traditional landline systems:
- HD Voice (High Quality Call): VoIP uses advanced voice compression technology that cuts down on the bandwidth required; you get much better sound quality when you are calling someone through VoIP. Today’s VoIP systems have noise reduction and echo cancellation for business calls.
- Integrated Systems: VoIP plays well with other tools, including CRM systems, helpdesks, email systems and business applications. This integration also helps to streamline workflows where calls are logged automagically, customer data gets populated while on the call, and communication gets fed into analytics systems.
- Provides Business Continuity: With cloud VoIP, your business can remain operational despite any unexpected emergencies or outages. You can easily route calls to mobiles, home offices, or resilience sites, ensuring your business remains connected even when your office is busy.
- Time-Saving Automation: VoIP solutions have smart technologies such as auto-attendants, call routing, voicemail-to-email transcription and automated call distribution. These capabilities eliminate manual call controls, minimise wait times, and help you get calls from the intended party in a timely manner.
- Mobile-Friendly Tools: With VoIP you can use your business’s phone system on a smartphone, tablet, or computer connected to the internet. Complete phone service with apps that offer the same features as your desk phones but are accessible anywhere for remote and hybrid workforces.
- Performance Insights: View real-time and historical analytics that track call volume, wait times, agent performance and customer satisfaction metrics. These learnings support data-driven decisions to enhance customer service, right-size staffing levels and pinpoint opportunities for training.

FAQs
A softphone, at its core, is an app (on your computer, mobile device, or tablet) that lets you make and receive phone calls over the internet using a business number and features.
It makes any device a complete desk phone by replacing the wired handset on your desk with software that you can put straight onto your personal device. Imagine some of those apps, like the mobile app for Zoom or RingCentral: that’s a softphone.
For a typical UK small business of, say, 5 to 10 people, you should expect to pay between £50 and £200 per month in total subscription fees for a system with the functionality you need.
A typical plan is anywhere from £6 to £20 per user, per month. If you use softphones, there’s often no upfront hardware cost, but you may want to purchase IP desk phones for a more traditional office.
Yes, you are almost always able to. This technique is known as number porting. That’s something that your new VoIP provider will take care of for you. You’ll need to obtain authorisation documents from your current provider.
It generally takes between one and two weeks, and there is no disruption in service; it means the number moves over to the new system. Please verify porting eligibility and schedules with your new provider before signing up.
