Voice quality recovery after a regional MOS drop

A financial-services back office routing inbound voice through a single peer in EE/ME saw MOS scores degrade from 4.2 to 3.4 over a two-week window. Customer complaints followed almost immediately.

The challenge

The degradation was real but intermittent, and the existing provider's diagnostic output was effectively a 'within SLA' page. Customers needed a real fix in days, not the next quarterly review.

Our approach

Activated diverse upstream peers via GlobalXess for the affected destinations, switched the route in real time, and ran AI-Enhanced Call Quality Monitoring across both legs in parallel for one week to validate the move.

Outcomes

  • MOS restored from 3.4 to 4.2 within a 48-hour window.
  • Jitter under 20ms across the affected destinations after the switch.
  • Customer complaints to the back office dropped to baseline within one week.
  • Diverse-peer routing now standard for that customer across all destinations.

"It is one thing to claim five-nines availability. It is another to swap a route by the end of the day and have the data prove the fix."
