Yeastar vs Grandstream PBX

Pick Yeastar when

  • SMEs wanting cloud or self-hosted PBX
  • MSPs and resellers managing phone systems
  • Teams migrating off 3CX
  • Multi-site businesses needing branch connectivity

When Yeastar is not a fit

  • Tiny teams that just need a few phone lines
  • Buyers with strict vendor-origin or data-sovereignty policies
  • Anyone unwilling to patch and secure a PBX themselves
  • Enterprises wanting fully managed, zero-touch UCaaS
