Sound familiar?
Your phone system is holding you back
Most businesses pay too much for a phone system that does too little.
Locked into Expensive Contracts
Long-term commitments with termination fees. Your provider counts on you being too invested to switch.
Aging Hardware That Breaks
On-premise equipment needs constant maintenance. You need dedicated IT staff just to keep phones working.
No Remote Work Support
Calls forwarded to personal phones. Lost call logs, no visibility, and your team gives out personal numbers.
Hidden Fees and Surprises
Add-on charges, support surcharges, per-feature pricing. The bill never matches what they quoted.

FAQ
Frequently asked questions
What is Nova Cloud PBX?
Nova is an AI-powered cloud phone system that replaces traditional hardware PBX. It provides voice, messaging, and advanced features like intelligent routing, voicemail transcription, and sentiment analysis—all managed through the cloud with no on-premises equipment.
Is there a contract?
No long-term contracts required. Nova operates on month-to-month billing with 30-day cancellation notice. No termination fees, no penalties for scaling down. We earn your business through exceptional service, not lock-in agreements.
Can I keep my phone numbers?
Yes, you can port existing numbers to Nova. Porting typically takes days to a few weeks, depending on your current carrier and number type. We handle all carrier coordination and paperwork at no charge. You can also order new numbers instantly if needed.
How does migration work?
We handle the entire migration process. Porting typically takes days to a few weeks, depending on your current carrier and number type. We configure call flows and auto-provision your phones (SIPSTACK does not sell phones; buy supported models from any retailer or reseller). Parallel cutover ensures zero downtime—most businesses go live in 2–4 weeks.
Where is my data stored?
Call recordings, voicemail, and other PBX media are stored in Canada if you are billed in Canadian dollars, or in the US if you are billed in US dollars. Our primary database and self-hosted AI run in Canada. Some data flows cross the Canada–US border; our privacy policy lists each one and the sub-processors involved.
What phones are supported?
Any SIP-compatible phone works with Nova, but we recommend auto-provisioned Yealink and Polycom models for optimal performance. You can also use the Pulse mobile app (iOS/Android) or SIPSTACK Connect desktop app (Windows/Mac/Linux) without physical phones.
What about E911?
E911 emergency calling is included at no extra cost. Every location is registered with local emergency services, and 911 calls automatically include your exact address. Remote workers can register their home address through the mobile app for proper emergency routing.
What CRM integrations are available?
Nova integrates with major CRM platforms including Salesforce, Zoho, Zendesk, and HubSpot. Features include screen pop, click-to-dial, auto-logging, and call recording sync. Full REST API and webhook support for custom integrations.
Can I get help with hardware and on-site installation?
Yes. Our authorized channel partners handle hardware sourcing, on-site installation, phone provisioning, and ongoing managed support. They are local IT providers who specialize in SIPSTACK deployments. Find one near you at sipstack.com/partners/find, or set everything up yourself through Switchboard — Nova is fully self-service.
