About Telzio
Telzio is a cloud business phone system that bills by usage (minutes, texts, and numbers) instead of per user, so every plan includes unlimited users and the full feature set. It covers call flows, IVR, call queues, SMS, fax, and call recording through a web dashboard, web phone, and mobile app, and it is HIPAA, GDPR, and SOC 2 Type 1 compliant, which makes it a common pick for healthcare and emergency services.
Pros & Cons
Pros
- No per-user fees: unlimited users on every plan, which is cheaper for teams with many occasional callers
- All features (call queues, IVR, recording, SMS, fax) included without tiers or add-on licenses
- Visual call flow editor that reviewers rate as easy to use
- HIPAA, GDPR, and SOC 2 Type 1 compliant, suited to healthcare and emergency services
- Strongly rated human support and a dedicated account manager (Capterra customer service 4.8/5)
- No setup fees and a 30-day money-back guarantee
Cons
- Usage-based billing makes monthly costs less predictable for high-volume calling teams
- Lower volume rates and MMC plans require talking to sales
- Some reviewers report occasional dropped calls and glitches in the newer mobile app
- Compatibility with some third-party desk phones (for example Grandstream) can be inconsistent
- Fewer native CRM and helpdesk integrations than larger UCaaS providers
