I have a network with a UC500 connected to a 3750 switch going through an ASA.
The ISP is currently having problem, so the site will be offline overnight.
I have no experience with VoIP, so will this be a problem in the morning? When the WAN comes back up, will the VoIP system resume? Will there be any sort of synching issues I'll need to address?
Any heads up will be very helpful.
