Start: Thursday 19 November 2026, 21:00 (UK) End: Friday 20 November 2026, 01:00 (UK)
Affected services: SIP Connect (outbound calls)
Details: We will be installing performance improvements to the checks carried out when outbound calls are placed, so that calls connect quickly and reliably at busy times and for high-volume accounts. We will also be aligning configuration across our SIP Connect servers.
Expected impact: - Calls in progress will not be affected. - A small number of new outbound call attempts may fail for a few seconds during short parts of the window and succeed on redial. - Inbound calls are not expected to be affected. - No action is required from customers.
If you experience any issues after the window, please contact our support team quoting "Maintenance 19 November".
