i would still build a new cos and let it delete the msgs for you.. an anouncement service needs to be in app builder anyway.. those people that left msgs never got a call back.. not great way to run a system.. the onlt customer that i worked for that deleted unread msgs in bulk was a county gov.. there reasoning was the cust was not going to call a different county for a permit, so they could call back..
