Communication APIs are best-in-class for developers who need to embed calling, SMS, or video into their own apps
Flexible seat licensing lets you mix and match plan tiers across different teams in the same organization
Starting price of $19.99/user/month undercuts most major competitors like RingCentral and 8x8
Global infrastructure strengthened significantly since the Ericsson acquisition in 2022
Number availability in 80+ countries makes it strong for international businesses

Admin portal feels dated with clunky navigation and settings buried in illogical submenus
Customer support wait times are notoriously long, especially on Mobile and Premium plans
The Basic plan is too stripped-down — no call recording, no CRM integrations, no call groups
Historical reputation for aggressive annual contracts and surprise early termination fees
Team messaging feature is bare-bones compared to dedicated platforms like Slack or Teams

Interface designed like a messaging app — immediately intuitive without any VoIP learning curve
Shared phone numbers let whole teams manage calls and texts to one business number collaboratively
Built-in CRM with contact tagging, notes, and conversation history eliminates need for a separate tool
At $15/user/month, one of the most affordable business phone options with no user minimums
Unified conversation threads combine calls, texts, and voicemails in chronological order per contact

No IVR menu system, call queuing, or advanced routing on the Starter plan
No desk phone support — softphone only through desktop and mobile apps
International calling rates are per-minute with no unlimited bundles available
Analytics and reporting are basic compared to RingCentral, 8x8, or Dialpad
Not suitable for companies with 50+ employees or complex enterprise call routing requirements
