We have been advised that Manx telecom will be carrying out some planned works on their core network which should be considered as at risk. This may affect calls over our SIPSIM service We have a requirement to migrate the voice interconnect of one of our upstream carriers to new connectivity links. Traffic will be changed in 2 phases over 2 days on 2nd and 3rd February. We do not anticipate any service impact however, there is an increased risk of disruption. The service will be closely monitored and will be reverted if problems occur. Maintenance Window From: 02/02/2021 09:00 - 16:30 GMT To: 03/02/2021 09:00 - 16:30 GMT
