Please be advised of the following maintenance window scheduled on Friday, 2nd December and Saturday, 3rd December 2016to IP Voice Services. Date: Friday 2nd December 2016 Start time: 2000 GMT Date: Saturday 3rd December 2016 End time: 0200 GMT Purpose: The Engineering Team will be performing works to add RAM to one of the servers in a Call Processing clusters and remove some legacy equipment from the primary datacentre. Services Affected: IP Voice Services Impact: In regards to the Call Processing cluster, these works will impact the primary server in the cluster, so call processing will be redirected to the secondary. The works relating to this will not begin before 2200. Due to the way that users are distributed within the platform these works will impact about 20% of users. Due to the nature of the works there will be a brief period of no more than 15 minutes, where users may experience excessive post dial delay or the brief inability to make or receive calls. The Engineering team will be working to make sure this is kept to a minimum and carried out at a time which impacts as few users as possible. Regarding the equipment removal, all equipment is no longer in active use; services are simply at risk due to the fact that Engineers will be working in racks with active equipment. Our Engineering Team will be closely monitoring all systems and services, as well as the above, to ensure any unexpected disruption is as brief as possible if experienced. Comtec is tracking this issue under ticket KZP-994-83945.

[VoIP UK] Service Alert 2nd November 2016 - Update 2

This is an incident notification regarding VoIP UK voice services. Date: Wednesday, 2nd November 2016 Start time: 15:14 GMT (UTC+0000) End time: 15:47 GMT (UTC+0000) Services affected: IP voice services using VoIP UK. BT services were unaffected. Report: Comtec NOC observed a drop in all registrations and an inability to register with VoIP UK. We have received the root cause analysis and remedial action from our vendor as follows: "We have experienced a service affecting problem as documented above. Our network operations team tracked and repaired. More than one customer region was affected and as such our customer support lines were very busy during and shortly after the time window above. Symptoms Customers may have experienced problems dialling out and may not have been able to receive calls. Most customer systems self-repaired, however it may have been necessary to restart some customer based equipment to bring back into service. Technical A customer programmatic event causing a system loop prevented normal fast database access. As a result outbound calls failed to be authorised in a timely manner and inbound calls may have been blocked for some customers. The immediate cause was identified, removed and remedial action was taken to bring stressed network components back in to normal operation. Further to this a development case has been raised to prevent a re-occurrence." Comtec NOC was tracking this issue under ticket [#DCX-370-12304]. This is the final update.
