Since 2009, net-iva.com has designed and deployed PBX systems for businesses of all sizes. Whether you need an on-premise Asterisk PBX, a cloud-hosted solution, or a hybrid setup, we deliver reliable, feature-rich telephone systems with 99.99% uptime.
On-premise, cloud, or hybrid — we've got you covered
Complete control with hardware installed at your location. Ideal for businesses with existing infrastructure, strict security requirements, or 50+ users. Full customization with Asterisk or FreeSWITCH.
Fully managed cloud PBX with no hardware to maintain. Perfect for remote teams, multi-location businesses, and companies that want to avoid CAPEX. Includes auto-attendant, voicemail-to-email, and mobile apps.
Combine on-premise and cloud. Keep local extensions on-site while using cloud failover, remote workers connect via cloud, or integrate with cloud contact centers. Best of both worlds.
