## Summary

JustCall is a capable plug-and-play application for American sales teams, but for Indian companies looking to scale, its per-user pricing model quickly becomes a significant seat-based tax. Billing in USD means you pay not just for calls but also for software overhead and currency conversion. Vobiz offers a purely programmable infrastructure model. By moving your communication engine to Vobiz, you pay only for the minutes you use, in INR, with full GST tax benefits. This lets you scale from 10 to 1,000 agents without subscription bloat on your monthly burn, while ensuring Tier-1 delivery across the Indian telecom grid.
