Some customers have been experiencing irregular phone call behaviour - such as when incoming calls are set to ring multiple phones, some phones carry on ringing after the call has been successfully answered elsewhere.
We have been investigating the problem, and have planned a software upgrade on some of our back-end servers for 6AM Thursday morning which will then enable some further configuration changes thereafter to improve the situation.
Our early morning work is sell under way, there will be a brief disruption to services at around 06:40-07:00 which will cause new calls to not connect for few short moments.
The disruption was short lived and didn't affect calls that were in progress.
