Voip phone volumne resetting

[colonelklenk]

I was wondering if there is any way to set the volumne on a VOIP system, system wide. We have a branch office and some of the phones (that is the weird part that not all the phones reset)as soon as there is a power glitch, the volume will reset back to the lowest volume, which employees in the laundry room don't notice as it is loud in there, and it isn't until the end of the day that they realize they haven't received any phone calls and they have tons of messages that they have to go through. I know that on our BCM sites we can choose to pick system settings.

thank you
