C15 Roadmap & Release 22

We’re excited to launch Release 22—our most advanced update yet. It delivers smarter controls, deeper customization, and long-term reliability.

Key improvements include enhanced handling of TTY messages with Wireshark support, flexible call history recording, new Stir/Shaken override options for better traceability, and real-time call limit tracking with an upgraded interface.

Plus, starting March 25, 2026, SIP code 603+ will notify callers when calls are blocked due to analytics, in line with FCC regulations.
