Pulse Assurance Diagram

Automated globally distributed testing for your SIP infrastructure.

Stop Chasing Silent Failures

Traditional ICMP and port monitoring miss the most critical VoIP issues. Pulse is built specifically to detect what others can't.

One-Way Audio

Signals "200 OK" but carries no audio. Pulse RTP analysis catches this instantly.

Ghost Registrations

Endpoints appear registered but signaling is broken. Pulse verifies the full auth path.

Trunk Degradation

Intermittent call failures due to upstream issues. High-frequency Pulse tests provide the proof.

Latency Spikes

Post-dial delay and media latency identified through global infrastructure testing.
