Security & Business Continuity
Keep communicating — no matter what.
Your phone system is critical infrastructure. DVGVoIP's hosted 3CX platform is built with layered security and automatic failover so your business keeps communicating.
Built-In Security at Every Layer
Most VoIP security incidents come from poorly configured systems — open SIP ports, weak credentials, or unpatched software. DVGVoIP's managed 3CX platform eliminates these risks by default.
Our hosted infrastructure is monitored continuously for unusual call patterns, toll fraud attempts, and unauthorized access. When something looks wrong, we act before it becomes a problem.
Every DVGVoIP system ships with 3CX's full security stack enabled out of the box. There's no checklist for your IT team — it's secure from day one.

Business Continuity — Stay Reachable When It Matters
Downtime means missed calls and missed business. DVGVoIP's hosted platform gives you multiple layers of failover.
Automatic Failover
If your internet connection drops, calls automatically reroute to a backup destination — a mobile number, another office, or voicemail — with no manual intervention required.
Mobile App Fallback
Staff with the 3CX mobile app can continue making and receiving calls over cellular data even when the office internet is down. Your business number stays reachable.
Cloud-Hosted Resilience
Your PBX runs in DVGVoIP's managed cloud — not in your office. A local power outage, hardware failure, or flood doesn't take down your phone system.
Automated Backups
Your 3CX configuration — extensions, call flows, voicemail greetings, call recordings — is backed up automatically. Recovery from any failure is fast.
Toll Fraud Protection
3CX's SBC monitors for abnormal call patterns that indicate toll fraud. Suspicious activity is flagged and blocked automatically before it costs you money.
No On-Site Hardware to Fail
Traditional on-premise PBX hardware fails without warning and can take days to replace. With DVGVoIP's hosted system, there's no single point of failure in your office.
Why This Matters for Northern Ontario
Northern Ontario businesses face unique continuity challenges. Severe weather, power outages, and limited local ISP redundancy make it critical that your phone system can survive disruptions that would knock out traditional on-premise equipment.
With DVGVoIP, your PBX is off-site. Whether it's a winter storm in Thunder Bay or a power outage in a remote community, your cloud-hosted phone system keeps working as long as your staff have any internet or cellular connection.
- Callers always reach someone — even during local outages
- Staff work from any location using the mobile app
- No emergency hardware replacement calls to make
- DVGVoIP monitors your system around the clock
CRTC E911 Compliance
DVGVoIP provides fully CRTC-compliant E911 service. Your registered business address is transmitted to emergency services when 911 is dialled from your system.
For businesses with remote or work-from-home staff, we train your team to keep their 3CX registered address current — so emergency services always know where to send help.
- E911 registration included on all plans
- Staff onboarding covers E911 address updates
- Compliant with CRTC VoIP 911 requirements
Who Needs This Most
Security and business continuity matter more in some industries — but every business needs to stay reachable.
Healthcare & Clinics
Patient calls can't go unanswered. DVGVoIP's automatic failover ensures a local internet outage never results in missed appointments or unreachable on-call staff.
Legal & Financial Services
Encrypted voice calls and detailed call records give law firms and accountants the audit trail and compliance documentation they need.
Remote & Resource Operations
Mining, forestry, and construction companies in Northern Ontario's remote communities need a phone system that keeps working when local infrastructure is unreliable.
Businesses Replacing Aging Hardware
Traditional on-premise PBX hardware fails without warning and takes days to replace. Hosted 3CX eliminates that single point of failure entirely.
