Telnyx is a Big Fish
Pros
- Responsiveness: Typically quick to reply to technical support chats.
- Availability: Large team accessible via email, chat, and phone.
- Innovation: Regularly adds and tweaks features on the web portal that always looks clean and modern.
Cons
- Number testing: Currently I need to call our fax numbers manually to confirm fax tones. It would be useful to test numbers in bulk from the portal.
- Troubleshooting: Currently, samples are needed for each fax transmission when there are issues. And those samples need to be within 24-48 hours. It would be useful if Telnyx could do a health check out proactively to gather information on high failure counts prior to customer reports.
- Transparency with system issues: We've run into scenarios where we wanted information on system-wide fax failures, but when the issues were resolved we didn't get root cause analysis.
Most Important Features
- Availability to troubleshoot fax issues.
- Large pool of available area codes.
- Automated communications: Porting updates, new number acquirement, etc.
Return on Investment
- Positive mostly: The easy-to-use interface and availability of numbers has resulted in us using Telnyx as our primary carrier.
