The Fundamental Difference
VoiceFleet and JustCall solve different problems. VoiceFleet replaces human receptionists with AI voice agents that answer calls 24/7, handling appointments, FAQs, and lead qualification autonomously. JustCall provides infrastructure for human sales and support teams to make and receive calls efficiently.
Pricing Reality Check
VoiceFleet: Flat-Rate Simplicity
- Starter: €49/month (unlimited calls)
- Growth: €199/month
- Pro: €599/month
- No per-user fees, no hidden charges for call volume
JustCall: Per-User Scaling
- Team Plan: $29/user/month (minimum 2 users = $58/month base) [1]
- Pro Plan: $49/user/month (minimum 2 users = $98/month base) [1]
- Additional Costs:
- Extra phone numbers: $6-10/month each [1]
- Overage charges: $0.02/minute beyond plan limits [1]
- Setup complexity: "API setup and full integration take a long time" [6]
Cost Comparison Example: A small clinic needing 24/7 coverage would pay €49/month with VoiceFleet. With JustCall, covering the same hours with human staff would require multiple agents across shifts, each costing $29-49/month minimum—before considering the actual salaries of those agents.
The AI Cost Advantage
AI voice agents reduce traditional call centre costs by up to 70% [4]. Human receptionists cost €30,000-50,000 annually (including benefits), while AI solutions like VoiceFleet cost €588-7,188 annually [4].
Real-world example: Morrison & Associates law firm implemented AI voice booking and slashed administrative costs from €167,000 to €60,000 per year—a saving of €107,000 annually [4].
Feature Comparison: Two Different Tools
Where VoiceFleet Excels
- 24/7 Autonomous Operation: No human staffing required—AI handles every call consistently
- Instant Setup: Configure in minutes vs. JustCall's "lengthy API integration" [6]
- Unlimited Scaling: Handle 100 simultaneous calls at the same €49-599/month cost
- Predictable Costs: No per-user scaling or surprise overage charges
- 100% Consistency: AI delivers identical quality on call 1 and call 1,000
Where JustCall Excels
- Human Agent Infrastructure: Built for teams making outbound sales calls [2]
- Advanced CRM Integration: Deep two-way sync with Salesforce, HubSpot, Zoho [2]
- Power Dialling & SMS: Auto-diallers and SMS campaign automation for sales teams [2]
- Call Analytics: AI call scoring, sentiment analysis, agent performance dashboards [2]
- Real-Time Agent Assist: Live suggestions during calls to help reps handle objections [2]
The Technical Reality: Setup & Reliability
VoiceFleet: Designed for non-technical small business owners. Setup in minutes.
JustCall: Requires technical integration. Customer reviews note: "API setup and full integration take a long time, and the software still has some glitches and bugs" [6]. Users report "major lag on calls," "connectivity issues," and "dropped calls" [6].
JustCall's 4.2/5 rating reflects solid functionality, but with caveats around "unclear billing practices" and "costly add-ons" [6].

- Restaurant: Handles reservation calls during busy service (no staff pulled from tables)
- Salon: Books appointments outside business hours (capture after-hours callers)
- Professional Services: Qualifies leads and answers FAQs while you focus on billable work

ROI Timeline
AI voice agents typically achieve positive ROI within 3-6 months [4]. Companies see average returns of $3.50 for every $1 invested in AI customer service [4].
JustCall's ROI depends entirely on how effectively your human team uses its features—the software is an enabler, not a replacement for labour costs.
The Bottom Line
VoiceFleet and JustCall aren't direct competitors—they serve different needs:
Choose VoiceFleet if you want to eliminate reception staffing costs while gaining 24/7 coverage. Best for small-to-medium businesses handling repetitive inbound calls (appointments, FAQs, enquiries).
Choose JustCall if you're managing a human sales or support team and need infrastructure for outbound calling, CRM integration, and agent performance management.
Many businesses find they don't need JustCall's complexity. If 80% of your calls are "What are your opening hours?" or "I'd like to book an appointment," VoiceFleet's AI handles that at a fraction of the cost—without the per-user fees, setup complexity, or reliability issues that JustCall users report [1][6].
