RTP Tester Analysis
As Of Thursday 12th of March 2026 12:27:43 PM EDT
MOS Score of 3.5 and above considered good quality. MOS Score above 3.0 and below 3.5 considered fair quality. MOS Score below 3.0 considered poor quality.
Our call transmitter is on a Texas (TX) cloud instance. Receivers are in cloud instances in California (CA), New York (NY) and Ontario (ON). So every call traverses the nation along a different path from TX to NY, TX to CA or TX to ON. Every call uses a randomly assigned RTP Server in the same percentages as registering subscribers. The TX transmitter calls every receiver, every minute and plays a 45 second audio recording. The receivers answer the call and play 45 seconds of audio. The transmitters and receivers all operate on a minimal linux cloud server with 1GB Memory, 1 vCPU Core and 1TB monthly Transfer to most closely mimic a typical subscriber.
