We have a SV8300 in a hotel connected to a Galaxy Lightspeed PMS system. When customer sets an individual wake up call from the PMS, everything works fine. When customer sets a group wake up call from the PMS, wrong time is entered in the SV8300. For example, set 7:30am group wake up call from the PMS (ie. 5 rooms), info is sent to SV8300, check wake up calls on the SV8300, wake up calls for those rooms says 6:07am, and rooms ring at 6:07am. Reports from the PMS say wake up calls set for 7:30am. Has anyone came across this? PMS issue? SV8300 issue?

Might I suggest checking Daylight saving settings on both systems. It may not be the cause but a one hour time difference to me screams daylight saving.

That's something to check. Thanks.

It looks like it was a Property Management System issue.

Having fun with the same myself at the moment, just about to cut over a 9300 with 400+ extensions and just tonight found a bug on the voicemail where notifications of failed alarm calls can't be accessed. The voicemail asks for your security code but then doesn't listen for it, so you can never cancel the notification.
