VoIP & UCaaS Migration

Genesys to 3CX Migration

Q: Can users keep familiar call flows?

Yes. Infrastructure Shift documents existing auto attendants, IVRs, queues, ring groups, voicemail behavior, schedules and routing rules before rebuilding them in the target platform.

Infrastructure Shift helps organizations move from Genesys to 3CX with a structured migration process focused on uptime, call quality, number ownership, user adoption and long-term supportability.

Modernize voice communications without disrupting the business

Phone system migrations are business-critical projects because customers, vendors, sales teams, support teams and leadership rely on voice services every day. A successful Genesys to 3CX Migration project requires more than moving extensions. It requires a complete review of numbers, call paths, call queues, IVRs, emergency calling, devices, remote users, carrier contracts, internet reliability and user expectations.

Infrastructure Shift evaluates the existing platform, documents how calls currently flow, identifies carrier and device dependencies, and builds a practical migration roadmap. The goal is to move your organization into a modern 3CX, SIP, cloud PBX or integrated Teams voice architecture while protecting customer service and minimizing downtime.

Why organizations migrate from Genesys

Organizations usually consider voice platform migration because monthly costs have increased, contracts are difficult to manage, legacy PBX equipment is aging, remote users need better support, call reporting is limited, or the business wants more control over SIP trunks, number ownership and system administration. Infrastructure Shift helps convert those business goals into a reliable technical plan.

Migration outcomes

Lower recurring voice platform costs where possible
Improved control over numbers, SIP trunks and call routing
Modern softphone, mobile app and web client access
Clear IVR, queue, ring group and voicemail recreation
Documented emergency calling and carrier requirements
Post-cutover support for users and administrators

Infrastructure Shift VoIP migration process

1. Discovery

We inventory phone numbers, extensions, call flows, IVRs, queues, ring groups, desk phones, softphones, users, sites, carriers, fax lines, analog lines and emergency calling requirements.

2. Voice Architecture

We design the target 3CX, SIP trunk, Azure, AWS, Teams integration or hybrid voice environment with attention to call quality, security, resilience and administrator control.

3. SIP & Carrier Planning

We coordinate SIP trunk selection, number porting requirements, temporary forwarding, caller ID, E911, failover routing and cutover timing.

4. Build & Pilot

We configure trunks, inbound rules, outbound rules, IVRs, queues, ring groups, voicemail, recordings, office hours, users and devices, then validate with pilot testing.

5. Port & Cutover

We manage the go-live window, test inbound and outbound calls, validate emergency calling, confirm routing, support users and coordinate with the carrier.

6. Support & Optimization

After cutover, we tune call quality, adjust routing, help users with apps and phones, document the system and provide administrator handoff.
