Frequently Asked Questions
1. VoIP vs traditional phone lines — what is the difference?
VoIP (Voice over IP) routes calls over your internet connection instead of copper phone lines. This eliminates per-line charges, gives you enterprise features like auto attendant and call queues at no extra cost, and lets employees use their office number from a mobile app anywhere. Traditional lines are simpler but far more expensive per call path.
2. What happens if the internet goes down?
We configure automatic failover — incoming calls route to mobile numbers or a backup location. For offices that need guaranteed uptime, we can deploy an on-premise survivable gateway that keeps local calling working even during an ISP outage. Most clients also keep one analog line for 911 and emergency backup.
3. Can I keep my existing phone numbers?
Yes. Number porting is standard — we handle the paperwork with your current carrier and typically complete ports within 2-4 weeks. During the transition, we configure call forwarding so you never miss a call.
4. Do you support remote and hybrid workers?
Absolutely. Every system we deploy includes a mobile app and/or softphone that lets remote employees make and receive calls using their office number from a laptop, smartphone, or home IP phone. Call quality is identical whether they’re in the office or working from home.
5. How much does a new phone system cost?
A typical 20-user cloud VoIP deployment — including desk phones, setup, and training — ranges from $4,000-$7,000 upfront with monthly service around $20-30/user. On-premise systems have higher upfront cost but lower or zero recurring fees. We provide a fixed quote after the site walk — no surprises.
