Common Challenges We Solve

The problems businesses face that led us to build VoiceInfra

High Support Costs

Hiring, training, and retaining customer service staff is expensive and time-consuming, especially for 24/7 coverage.

Missed Opportunities

Calls go unanswered after hours, on weekends, or during busy periods, leading to lost leads and frustrated customers.

Inconsistent Service

Human agents have varying skill levels, bad days, and different approaches, leading to inconsistent customer experiences.

Complex Integration

Most voice AI solutions require changing phone carriers or complex technical implementations that disrupt existing workflows.

Frequently Asked Questions

We support PBX systems up to 20+ years old, including legacy Avaya, Cisco, Mitel, and Asterisk installations. If it supports SIP, we can modernize it.

No. Legacy modernization adds AI capabilities without changing your existing phone system operations. Your staff continues using familiar procedures while gaining AI benefits.

Typically 90% less than complete system replacement. Instead of $500K+ for new hardware and installation, you pay only for AI services while keeping existing infrastructure.

Gradual modernization is recommended. Start with specific departments, call types, or locations and expand AI capabilities over time based on success and requirements.
