Upgrade of our telephony system

Hello! On Wednesday 25 March between 05:00 and 09:00, Chalmers will upgrade our telephony system. This may cause shorter downtime throughout the day for calls and data via mobile phones, as well as landlines and group numbers. If you experience problems calling or surfing on your mobile, we recommend a restart to force it to reconnect to Telenor's network. The upgrade will result in your old voicemail will be deleted and replaced with a new one in the new system. Listen to and save old messages before March 25 if you want to keep them. More information about the upgrade and what it means for you can be found in the news feed or if you search for phone systems replacement on Chalmers' intranet.
