The answer to your first question is "No" on both counts to the best of my knowledge. Maybe you could have the telco program a timeout on the paging circuit so that it doesn't get hung for long periods of time.

Second Question: Are you sure the line in question is a Centrex line? I've never seen a Telus Centrex line that doesn't require a '9' to dial out (I have seen it on Allsteam Centrex lines though) Anyhow, it's a change that has to be made by the Telco.
