Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cresta

  • Cresta depends on the CCaaS platforms it integrates with, and NICE, Genesys and Five9 are all shipping native real-time assist and auto-QA of their own, so at renewal you may be paying twice for capability your platform vendor will bundle at a discount.
  • Pricing is not published and contracts are seat-based and annual at enterprise scale, which in practice means six-figure commitments and a procurement cycle measured in months rather than weeks.
  • Real-time guidance only pays back where conversation outcomes are measurable and repeatable, so support teams handling long, varied, low-volume cases rarely recover the licence cost.
  • Deploying real-time assist requires agents to accept on-screen prompting mid-call, and contact centres with strong union representation or experienced tenured agents frequently see adoption resistance that no amount of model quality fixes.
  • Automated quality scoring changes what agents are measured on, and organisations that switch from human QA without rewriting their evaluation rubric and appeals process create industrial-relations problems that surface months after go-live.

Vonage

  • MMS pricing not published publicly, requires sales team quote
  • International SMS rates can exceed $1.00 per message in some markets
  • Smaller developer ecosystem compared to Twilio

Answered from the vendors’ own pages

Vonage SMS API costs $0.00809 per outbound message and $0.00649 per inbound message in the US. There is no monthly minimum. Virtual phone numbers cost around $4.18 per month.
