FAQ
Frequently Asked Questions
How much does a business phone system cost in NH?
A small-office VoIP system with 10 desk phones starts around $5,000–$10,000 installed, including programming and training. Mid-size deployments of 30–65 phones with auto-attendant, voicemail-to-email, and paging integration typically range from $15,000–$40,000. Enterprise multi-site systems vary widely — contact us for a custom quote.
Cloud VoIP or on-premise PBX — which is better?
Cloud-hosted VoIP is ideal for distributed teams, remote workers, and organizations that prefer lower upfront costs and automatic updates. On-premise PBX gives you maximum control over hardware and call routing, and suits larger organizations with dedicated IT staff. We help you evaluate both honestly.
Can I keep my existing phone numbers?
Yes. We handle number porting from all major carriers — AT&T, Comcast, FairPoint, Verizon, and others — with minimal downtime. Most ports complete within 2–3 weeks.
Do you support remote workers?
Absolutely. Our cloud VoIP solutions include softphones, mobile apps, and call forwarding so remote staff stay connected from any location. Calls route seamlessly between desk, mobile, and home office.
What happens if the internet goes down?
We design failover routes — including cellular backup and automatic call forwarding — to keep you reachable during internet outages. No business should lose calls because of a single ISP failure.
Do you service and repair legacy phone systems?
Yes. We service and repair Avaya, Panasonic, Nortel, Lucent, NEC, Toshiba, and Samsung legacy phone systems across New Hampshire — whether we originally installed them or not. If parts are still available, we can keep your system running while you plan an upgrade.
Do you provide training for new phone systems?
Every phone system installation includes end-user training and administrator documentation. We also offer ongoing training sessions when you add staff or change call flows.

Our Phone System Installation Process
1. Site Walk
We visit your facility to understand your building, network rooms, staff workflow, and communication goals. We review your current phone bills, call volume, and growth plans so we recommend the right system — not the most expensive one.
2. Design and Scope
Our engineering team creates a detailed system design with phone placements, network requirements, cabling paths, and a fixed-price proposal. You see the full scope and cost before we pick up a tool. No change-order surprises.
3. Install and Configure
Our NH-based technicians install the complete system — cabling, network equipment, desk phones, paging speakers, and software configuration. We port your numbers, program auto attendants, set up voicemail-to-email, and test every extension before go-live.
4. Training and Support
Every installation includes end-user training and administrator documentation. We walk your team through day-to-day operations — transferring calls, checking voicemail, changing greetings. After installation, we provide 24/7 emergency support and optional maintenance contracts.

Arcomm Connect VoIP
Arcomm Connect is our own managed VoIP service — designed by our engineers, hosted in redundant data centers, and supported by our local team. Arcomm Connect gives you the simplicity of cloud phone service with the accountability of a local NH contractor. If something goes wrong, you call (603) 464-4600 and reach a technician in Hillsborough — not a call center overseas.
Arcomm Connect includes unlimited domestic calling, auto-attendant, voicemail-to-email, mobile apps, and failover routing. We handle number porting, phone provisioning, and network configuration. You focus on your business; we keep the phones working.
Cloud VoIP vs. On-Premise PBX
Cloud VoIP has become the right choice for most New Hampshire businesses. Platforms like RingCentral and Arcomm Connect eliminate the need for an on-site phone server, automatically apply software updates, and let you add or remove lines from a web portal. Remote workers connect from home with a softphone or mobile app — no VPN required. Monthly costs are predictable, and there is no hardware to maintain.
On-premise PBX systems like Mitel remain the right choice for organizations that want full control over their call data, need custom integrations with legacy software, or have reliable internal IT staff to manage the platform. We help you evaluate the trade-offs honestly so you choose what fits your business — not what generates the most recurring revenue for us.
Legacy Phone System Repair in NH
If your business is still running an Avaya, Panasonic, NEC, Nortel, or Samsung phone system, you are not alone. Many New Hampshire offices have reliable legacy hardware that still makes calls every day. When something breaks — a card fails, voicemail stops working, or you need to add an extension — Arcomm’s technicians can diagnose and repair it.
We stock replacement parts for legacy systems and maintain wiring diagrams for systems we originally installed. Even for systems we did not install, our technicians can assess, document, and support what you have. When you are ready to upgrade, we design the transition so there is no downtime.
