Our solutions for your call center app testing challenges

Solving the real performance, reliability, and integration risks behind modern call center platforms.

Unpredictable call volumes

Challenge

Traffic can surge 10–20x, and 72% of outages occur under unexpected load.

Solution

We simulate peak concurrency, regional spikes, jitter, and packet loss to keep routing, queues, and call flows stable at any scale.

Voice quality degradation

Challenge

Latency above 150 ms or jitter over 30 ms significantly reduces call clarity.

Solution

We recreate real network conditions and test across codecs and devices to secure consistent audio quality across all environments.

Complex routing and omnichannel paths

Challenge

Over 40% of call failures come from untested routing branches.

Solution

We map and validate all rules, skills, escalations, and voice → chat → email transitions to eliminate logic gaps and dead ends.

Fragile third-party integrations

Challenge

60% of operational incidents originate from CRM, WFM, or ticketing integrations.

Solution

We test API behavior, rate limits, and failure modes under load to ensure stable data sync and uninterrupted workflows.

IVR and speech recognition errors

Challenge

Speech recognition accuracy drops 15–25% with noise or strong accents.

Solution

We test IVR flows, DTMF paths, and STT/NLU accuracy in real conditions to reduce misroutes and improve automation reliability.

Breakages after frequent updates

Challenge

Constant queue changes and feature rollouts often disrupt routing and reporting.

Solution

We build automated regression coverage to maintain stable releases without slowing development.
