Where each one falls short

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

Five9

  • Prices are per concurrent user rather than per named agent, which changes what a seat means when shifts overlap
  • Voice is excluded from the Digital plan and requires a quote
  • Usage based charges apply on top of the per seat rate
  • Three of the five tiers publish no price at all

Twilio

  • Pricing becomes unpredictable with carrier fees and additional charges for compliance, recordings, and phone number rentals
  • Phone number rentals are required for every number used, with carrier fees varying by region and billed separately
  • Dashboard is not optimized for mobile use and logs are difficult to access
