Stuck on WebRTC connection failures. JMeter hits 50 concurrent threads. The softphone returns 403 Forbidden immediately after handshake. This happens on US1 environment. Need to validate capacity for 500 concurrent agents.
jmeter:
threads: 50
ramp_up: 10
loop_count: 100
env:
region: US1
sdk_version: 2.0.1
Why does this error occur at this concurrency level?
