VoIP Monitoring without the Missing Links

With global offices, wireless networks, and data traversing the public internet, troubleshooting VoIP performance is tricky. ThousandEyes brings a unique approach.

Get Deeper Insights into VoIP Traffic and Performance

ThousandEyes extends visibility across corporate networks as well as the public Internet, helping to solve issues from the branch through MPLS links and SIP trunks to service provider networks. Simulate pre-deployment capacity, monitor detailed performance metrics and see how QoS settings impact call quality.

See Exactly Where Performance Is Degraded

Detailed path visualization helps operators identify exactly which network nodes and links are responsible for quality
and availability issues. With information on end-to-end performance, and every hop in between, you won't waste time.

VoIP In Context

Data overlays map how routing affects voice calling experience, verify MPLS routes and ensure QoS levels using DSCP classes.

Detailed Call Metrics

Quality metrics — such as loss, jitter, latency, discards and mean opinion score (MOS) — show where, when and why performance changes.

Planning and Ops

Use voice monitoring for
pre-deployment capacity and routing planning to post-deployment performance troubleshooting.

Monitor On-Premises or Cloud Voice Services

Monitor voice performance of on-premises Unified Communication systems — such as Lync,
Avaya or Cisco UCM — or UCaaS systems — such as ShoreTel or RingCentral.
ThousandEyes VoIP Monitoring


For inter-office monitoring across local or wide-area links, VoIP calls
are simulated between Enterprise
Agents in branch offices.


To understand performance to external locations, VoIP calls are simulated between your offices and Cloud Agents located globally.

Tune to Your Network

ThousandEyes performs synthetic VoIP tests, using RTP and UDP, that can be customized to your VoIP audio codecs and QoS settings.
