Nuacom desktop application (softphone) minimum requirements.

Component	Requirements
Processor/Chip	Intel/AMD 64-bit Apple ARM M series
Physical RAM	8 GB of RAM
Hard Drive	2 GB of available hard disk space for the installation
Display	800 x 600 or larger
Maximum Resolution Scale	125% (More than that will make the app unusable)
Operating System	Microsoft Windows 10 and later MacOS 12 Monterey and later Ubuntu 14.04 and later Debian 8 and later
Protocol/Ports unobstructed to ensure desktop app functionality	HTTPS/TCP 443 - api.nuacom.ie HTTPS/TCP 443 - https://d2046zq7ft8yun.cloudfront.net/ WSS/TLS/TCP 443 - webrtc-gw.nuacom.net HTTP/TCP 443 - https://o273287.ingest.sentry.io STUN/UDP 19302 - stun.l.google.com RTP Port Range: 10000-30000 UDP
Audio bandwidth requirement	128kbps minimum
*Network card (recommended)	Ethernet 100BASE‑T, 1000BASE‑T, wireless (Wi-Fi)
**Audio input/output device	Speaker and Mic

*While the above is the minimum requirement for the app to run, we recommend using Ethernet instead of the WiFi network connection (network access method) for the best calling experience. This is to avoid possible WiFi interference in a very congested wireless spectrum.

**We recommend using a USB headset with noise-cancellation capabilities. This would significantly improve the user and especially the caller experience. USB is preferred, but a built-in jack of 3.5 mm and other standards should work (not tested).
