What to Expect

Phones at Guelph and Ridgetown campuses will briefly disconnect from the cloud system and automatically register with local SRST gateways.

During this time, only basic calling features will be available: internal extension dialing, PSTN calls, and emergency dialing.

Unavailable during the test: All advanced call processing features like call queues, call trees, call forwards and hunt groups and Voicemails.

Users may notice short service interruptions (up to 10 minutes) while phones re-register.
