Configuring the SIP
Phone Downloader
Use this section to configure the SIP phone downloader. The Local Device
Name needs to be changed to what ever your host is configured as.
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.
Choose one of the 2 Ethernet interfaces (recommend eth1) you want
this SIP phone downloader to use.
