4J Network Services is scheduling critical work on the NEC 2400 phone system (2/16/2017) after 5:00pm. The maintenance will occur from 5:00pm-9:00pm. In this case the work will involve no network outage, It will create cause intermittent telephone system downtime during the maintenance window. There is always the risks of outages during this time if things don’t go as planned. We will be working on the following:
- Isolate source of audio/call quality issues from SV9500 system to NEC 2400 system.
- Replace IP-PAD cards in NEC2400.
- Upgrade Firmware on IP-PAD cards.
2/17/2017 Follow up
- Modified location routing for all VOIP phones. This seems to improve call quality significantly. No other changes were made.
