Hybrid UCaaS Implementation: The Deployment Guide

Deploying hybrid UCaaS is more involved than spinning up a pure cloud system. There’s an on-site appliance to install, failover paths to configure, and a cloud layer that needs to sync with local infrastructure before anything goes live. Most of that complexity sits on Sangoma’s side of the table — but understanding what happens at each stage helps your team prepare, ask the right questions, and avoid delays that push back your go-live date.
This guide covers how Sangoma deploys hybrid UCaaS, what each phase involves, and how survivability and failover are configured during deployment rather than added afterward.
If you’re looking for a checklist of what your team needs to prepare on your end, see the Hybrid UCaaS Deployment Checklist.
In this article, we will cover the other half: what Sangoma does, and what to expect at each stage. (For readers in a manufacturing environment, Sangoma’s VoIP implementation guide for manufacturing covers the industry-specific considerations that apply before and during deployment.)
Key Components That Power Sangoma’s Hybrid UCaaS
Sangoma’s hybrid unified communications service combines cloud management with on-site reliability. Rather than relying entirely on internet connectivity, the architecture keeps voice traffic local where possible while using the cloud for centralized control and management. The following components are involved in every deployment.
The StarBox® Appliance
The StarBox® edge device sits at the perimeter of the customer’s internet connection, outside the firewall. Its primary function is keeping voice running during internet outages, and it does this through local survivability: internal calls stay within the local network rather than traversing the internet, so a WAN outage doesn’t take down the phones.
StarBox® also handles traffic shaping on both directions of the connection. It prioritizes voice packets and identifies slow network points, rerouting calls to avoid congestion. For failover, it supports dual WAN circuits, LTE backup, and analog POTS lines. When an outage occurs, calls continue on the backup path automatically.
The appliance arrives preconfigured before installation. Sangoma provisions it ahead of shipment, so on-site setup consists of physical installation and registration rather than configuration from scratch.
Business Voice Plus (Cloud Backbone and Management Portal)
Business Voice Plus (BV+) is the cloud layer where call routing, users, extensions, auto attendants, and sites are created and managed. Sangoma builds most of this configuration before the system goes live, then hands it to the customer for review and approval. After go-live, the BV+ portal is how admins make everyday changes: adding users, adjusting call flows, updating extensions, and pulling reports.
BV+ connects to multiple redundant data centers across the country. Devices automatically connect to the nearest data center for optimal performance, and intelligent call routing selects the most efficient path to reduce latency and maintain call quality.

TeamHub and Sangoma Meet (Collaboration Tools)
When the system goes live, users get access to the full business collaboration suite. TeamHub covers voice calling, chat, SMS, and presence. Sangoma Meet provides video conferencing. File sharing is included across both platforms. These tools are available on desktop and mobile clients from day one, so there is no lag between system activation and user access.
Phones and Network Layer
Sangoma supports its own hardware phones and a range of compatible third-party IP phones. The network layer requires PoE switching for phone power and VLAN segmentation to separate voice traffic from data traffic. StarBox® handles the VLAN configuration automatically: VLAN 41 carries dedicated voice traffic, and VLAN 42 routes to failover circuits. For organizations that want additional stability, Sangoma’s managed network and SD-WAN services are available as optional add-ons.
The UCaaS Implementation Workflow
Deployment follows a predictable six-phase sequence. The table below provides a high-level view before each phase is detailed.
| Phase | What Sangoma Does | What Your Team Does | Typical Timeframe |
|---|---|---|---|
| 1. Network Review & Requirements | Reviews LAN/WAN readiness, confirms failover option | Provides site access, network documentation, call flow requirements | Week 1 |
| 2. Business Voice Plus Buildout | Creates sites, users, extensions, call flows in the portal | Reviews and approves the configuration | Week 1–2 |
| 3. StarBox® Shipping & Site Prep | Ships preconfigured appliance | Prepares rack space, network drop, PoE switching | Week 2 |
| 4. On-Site StarBox® Installation | Installs and registers the appliance, provisions phones | Provides on-site access, confirms phone placement | Week 2–3 |
| 5. User & Device Activation | Activates softphones, TeamHub, Meet, voicemail, SMS | Coordinates user training in small groups | Week 3 |
| 6. Cutover & Final Validation | Handles number porting, final routing tests, monitors post-go-live | Confirms legacy system decommission readiness | Week 3–4 |
Phase 1: Network Review and Requirements
Before any configuration begins, Sangoma reviews the site’s LAN and WAN environment. This includes switching and cabling, bandwidth capacity, and the state of any existing infrastructure that will remain in place. The goal is to confirm the network is ready for voice traffic and identify anything that needs to be addressed before StarBox® arrives.
At this phase, the customer selects a failover option: dual WAN, LTE, POTS, or a combination. The decision gets recorded and built into the StarBox® configuration before it ships.
Call flow requirements are also gathered here: IVR menus, queue structures, routing logic, and hunt group behavior. Getting these details upfront means BV+ can be built accurately in Phase 2 rather than revised after go-live.
This is also when compliance requirements are confirmed. For organizations subject to HIPAA, PCI, or other data-handling regulations, the requirements around call recording, storage, and failover paths need to be established at this stage. Sangoma’s platforms support both, but retrofitting compliance requirements into a completed BV+ configuration and StarBox® setup adds unnecessary work. Confirming them now means they are built in from the start.
Phase 2: Business Voice Plus Buildout
With requirements in hand, Sangoma builds out the BV+ configuration. This includes creating all sites, users, extensions, call flows, auto attendants, and any queues or hunt groups identified in Phase 1. The work happens in the portal before anything is installed on-site.
Once the buildout is complete, the customer’s project owner reviews the configuration. This review is the checkpoint before the system moves forward. Changes at this stage are far simpler than changes post-installation, so Sangoma recommends thorough review and sign-off before Phase 3 begins. The BV+ buildout is the foundation everything else runs on.
Phase 3: StarBox® Shipping and Site Prep
Sangoma ships the preconfigured StarBox® appliance to the site. Because it arrives already provisioned, the local team’s preparation is primarily physical: clearing rack space, confirming a network drop is in place, and verifying that PoE switching is ready for the phones.
Before the installation technician arrives, Sangoma verifies that site prep is complete. This check reduces on-site delays and keeps the installation on schedule.
Phase 4: On-Site StarBox® Installation
A Sangoma technician installs the appliance, connects it to the network, and registers it against the BV+ portal. This is when the cloud and on-site layers are joined for the first time.
Phone provisioning follows installation. Desk phones are connected to the PoE switch, receive their configuration automatically from the portal, and are tested for extension registration and audio quality. Internal calling, paging, and failover are all verified before the technician leaves the site. Routing behavior is confirmed against the call flows built in Phase 2.
Phase 5: User and Device Activation
With the system installed and phones operational, Sangoma activates the remaining user-facing features: softphone clients, TeamHub, Sangoma Meet, voicemail, SMS, and presence. Users can reach the system from desktop apps and mobile devices from the moment activation is complete.
Training is coordinated during this phase in small groups rather than all-hands sessions. Smaller groups allow users to ask questions and walk through their specific workflows, which produces faster adoption than broad overviews. Admins receive separate instruction on the BV+ portal so they can manage the system without needing to contact support for routine changes.
Phase 6: Cutover and Final Validation
Sangoma manages number porting and the transition away from the legacy system. Final routing tests confirm that inbound and outbound calls behave as expected across all call flows. Failover is tested against the selected backup option.
After go-live, Sangoma monitors the system for a short stabilization period. Any routing anomalies, audio quality issues, or unexpected failover behavior are addressed during this window. Once the monitoring period closes, the system transitions to standard 24/7 support.
Multi-Location Deployments
Each location in a multi-site deployment gets its own StarBox® appliance, shipped preconfigured to that site. The six-phase workflow runs per site, not per company, so the process is the same whether the organization has two locations or twenty.
All sites are managed from a single BV+ portal regardless of how many are live. Call routing, user management, and reporting remain centralized. An admin making a change for a specific site does not need to log in separately or manage separate configurations.
For organizations with multiple locations, Sangoma phases the rollout in waves. A pilot site deploys first, and any lessons from that installation are incorporated before the next wave begins. The 3–4 week timeline applies per wave, not per location within a wave. Multi-location deployments of this kind are covered in more detail in Sangoma’s article on unified communications for franchises.
How Sangoma’s Support Handoffs Work
Support during a hybrid UCaaS deployment is not a single team handing off a ticket at go-live. It transitions through distinct stages as the deployment progresses.
During provisioning, the team responsible for BV+ configuration and StarBox® setup is the primary point of contact. At cutover, responsibility shifts to a go-live support team that monitors the system through the stabilization window. After that period closes, the account moves to Sangoma’s 24/7 US-based support, staffed from locations in Sarasota, Atlanta, and Huntsville. Each stage overlaps with the next so there is no gap during transition.
Day-to-day operations after go-live are largely self-service through BV+. Admins add users, adjust call flows, modify extensions, and pull call reports from the portal without opening a support ticket. StarBox® runs the survivability and failover functions in the background without requiring intervention: if a WAN outage occurs, calls shift to the backup path automatically and return to primary when connectivity is restored. TeamHub and Sangoma Meet are available through the same credentials users set up during activation, accessible from any device.
