What Are VoIP Phone Systems?

Key Advantages of VoIP Phone Systems

FAQs
VoIP (Voice over Internet Protocol) converts voice calls into digital data packets sent over the internet instead of traditional phone lines. When you make a call, your voice is compressed, transmitted as data, and reassembled at the other end in real time. Businesses can run VoIP on cloud-hosted platforms, on-premise systems, or a hybrid of both. Advanced Communication Systems deploys VoIP solutions built on Avaya and Cisco technology, configured for businesses from a handful of users to several thousand.
Most businesses save between 30% and 50% on monthly telecom costs by switching to VoIP. The biggest gains come from eliminating per-line fees, reducing long-distance charges, and consolidating voice and data onto one network. Businesses replacing aging PBX or T1 systems often see the largest savings. ACS can provide a side-by-side cost comparison against your current setup before any commitment.
Not necessarily. VoIP works with IP desk phones, softphone apps on computers or mobile devices, or a VoIP adapter that connects your existing analog phones to a new system. The right hardware depends on your call volume, workspace setup, and whether employees work remotely. ACS supplies and supports IP phones from Avaya and Cisco and will recommend the configuration that fits your environment.
Yes, for most businesses. Enterprise-grade VoIP systems from providers like Avaya and Cisco are designed for 99.99% uptime. The key variables are your internet connection quality and the redundancy built into the deployment. ACS engineers VoIP systems with failover options — including automatic rerouting to mobile devices during an outage — so your business stays reachable even when the unexpected happens.
Hosted VoIP plans for small businesses typically run $20 to $50 per user per month depending on the features included and call volume. On-premise VoIP systems carry a higher upfront equipment cost but lower monthly fees over time. The right model depends on your team size, budget structure, and how long you plan to use the system. ACS offers both and can build a custom quote based on your actual requirements.
The features that deliver the most value for the cost are: unlimited local and long-distance calling, auto-attendant (which reduces the need for a dedicated receptionist), call routing and ring groups, voicemail-to-email, and a mobile app for remote employees. ACS works with clients to identify which features they will actually use daily so they are not paying for capabilities that sit idle.
