Network Outage

Earlier today we experienced a brief service interruption affecting parts of our voice platform.

The issue was caused by an unexpected interaction between OpenSIPS, the platform that manages and routes phone calls across our network, and Homer, a monitoring system used by our engineers for call analysis and troubleshooting.

This interaction resulted in OpenSIPS consuming excessive server resources, causing call processing services to become unavailable. Unfortunately, diagnosing the root cause took longer than expected because the symptoms initially appeared to be a general OpenSIPS performance issue rather than a fault related to the monitoring platform.

What customers experienced

• Outbound and inbound calling services were unavailable during the incident period.
• Some call attempts may have failed or been unable to connect.

Resolution

• The Homer integration was isolated from the OpenSIPS platform.
• OpenSIPS services were restored and normal call processing resumed.
• Additional monitoring and safeguards are being reviewed to help prevent a recurrence.

We apologise for any inconvenience caused and appreciate your patience while the issue was investigated and resolved
