Scheduled Config Push - timeout

Quick question

If i send a config change to a R200 router, and that router is switched off, how long will cnMaestro wait before timing out.

We have had a customer move to a new house. We therefore need to disable their voip line in the old router so the new person moving in cannot use it. When the router is next booted up, we want the new config downloaded from cnMaestro - but that could be months or years away with the house being empty in that time.

If we set a new variable for the device and push out its config, will that device update in 12 months time when it is next booted up? Or will cnMaestro give up too early?

Nevermind it appears cnMaestro gives up immediately if the device is offline
