CAUTION: If using a dual download environment, two issues can arise: 1) The WAN link utilization can be stressed during a large download (especially if the primary server is down). For example, if you have a large number of phones pointing to a primary download server on the LAN and a secondary download server that sits across a WAN. If the primary building takes a power hit, the download server might take 15 minutes or more to recover, but the phones will all reboot in a few seconds and begin looking for their download. This will begin to flood the WAN link.

2)If there is a version mismatch, you could get into a situation where phones go into a continuous cycle of rebooting and downloading.
