[Comtec Announce] [IP Voice Services] Maintenance window 19th March 2016

[Adrian Williams]

Please be advised of the following maintenance window scheduled on Saturday, 19th March to IP Voice Services.

Date: Saturday, 19th March 2016
Start time: 0000 GMT
End time: 0400 GMT


Purpose:

The Engineering team will be performing works to upgrade the Session Border Controller Clusters to the latest patch which contains fixes for few outstanding issues and also provides improved resilience and stability. These SBC clusters currently serve Public IP Centrex customers and 'registering' SIP Trunking customers. Static/Enterprise SIP Trunk Customers will not be affected.

The upgrade will be done on the standby half of the HA Pair followed by failover, and the other half will be upgraded. 



Services Affected:

IP Voice Services



Impact:

We do not expect to lose registrations and connected calls as the other half of the SBC cluster will handle the registrations and call attempts.
The Engineering team will be closely monitoring all systems and services to ensure any disruption is as brief as possible, if experienced.
Comtec is tracking this issue under ticket GEF-682-38818
