Incident Report

Summary AI Generated

A bug introduced after a 5.4 upgrade caused devices using the DND softkey to send an incorrect cause code, routing incoming calls to the "Not Answered" setting instead of the intended DND treatment. The issue affected call routing behavior and persisted for approximately 157 hours while engineering developed and staged a fix. The resolution was deployed in two phases — a partial patch on October 23rd and a final fix implemented on October 24th — fully restoring correct DND and busy routing behavior.

Hello Partner, We have identified an issue with the device user's DND setting sending an incorrect cause code causing calls to follow the Not Answered setting rather than the DND setting. We have asked engineering to investigate the cause. Next update will be provided by 9AM tomorrow morning. Regards, WLC Management

Hello Partners,

Engineering has developed a solution that is being rolled out tonight that will address a portion of the DND/busy routing situations. The remaining call flows that aren’t fixed by this patch will be fixed next week with another patch. We will provide another update Monday morning.

Hello Partners,

We have tested a potential solution to the DND/Busy routing issue in our staging environment. Further testing will be done on a production account before engineering and development can come up with the actions needed for roll out. We'll have another update by 4PM.
