Performance Metrics
Note
- Unless explicitly mentioned, the performance numbers below are collected without raising any alarms or errors.
- The limiting factors are packet loss and retransmissions, unless anything is specified (excluding transcode).
- The core-wise usage is not mentioned, as in most cases the Default profile is used.
- SRTP Calls are executed from PKTART.
- TLS/SRTP is enabled at the Public side traffic. One TLS connection (Port) is used for all calls.
