After performing some changes on core equipment we have seen a significant uplift in the number of handsets successfully registering from approximately 14:50. The issue is ongoing and a number of customers remain affected, we are continuing to work on the incident as a priority. There are additional works planned over the next 30 minutes that should help to further improve the registration. On newly registered handsets we have had a small number or reports of one way audio, or no audio, which we are also investigating as a priority.
We will provide a further update in 30 minutes.
