3CX Alternative: Complete Yeastar UCaaS Platform Comparison for MSPs and VARs
The Problem With Your Current Setup
You know the drill. Something breaks, and the finger-pointing begins. Your SIP provider blames the PBX. The PBX vendor says it's a network issue. Your compliance consultant hasn't heard back from the carrier. Meanwhile, your customer is down and you're stuck in the middle.
And that's before we talk about the limitations that are costing you deals:
What 3CX Partners Are Running Into:
- Remote extension deployment requiring customer-premise SBCs
- No outbound call center capabilities
- No agent pause/unpause functionality
- No static agents—everything requires manual login/logout
- One shared wallboard for all queues
- No white-label options whatsoever
- A central management platform that lacks the tools to scale efficiently
- No macOS desktop client support
- Failover with 5-minute to 6-hour replication intervals
When your platform creates friction instead of removing it, every sale gets harder.
