This fact makes reducing the upgrade time even more important for providing voice services to users. With the recent release of the Cisco Unified IP Phones 8900 and 9900 models, the firmware update process has been changed to minimize the downtime of a phone during upgrade. The newer Cisco Unified IP Phones 8900 and 9900 models perform a firmware upgrade as a background process and the phone continues normal operations. The new firmware is stored as an inactive image on the phone, and then when validated, the phone restarts and switches to the new firmware image. This process limits the service outage of the phone to 1-2 minutes (while restarting). The background downloading of a new firmware does not exclude the newer phones from taking advantage of the Peer Firmware Sharing feature. You can use both to greatly reduce the total time for all phones to upgrade<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> cisco-voip-bounces@puck.nether.net [mailto:cisco-voip-bounces@puck.nether.net] <b>On Behalf Of </b>Ahmed Elnagar<br><b>Sent:</b> Thursday, July 15, 2010 7:20 PM<br><b>To:</b> STEVEN CASPER<br><b>Cc:</b> cisco-voip@puck.nether.net<br><b>Subject:</b> Re: [cisco-voip] Issues with Peer Firmware Update, anyone?<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Sorry I mixed this with another feature…but I found why I have negative feedback about it and decided before not to use it as much as I can:<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><a href="https://supportforums.cisco.com/message/3062951">https://supportforums.cisco.com/message/3062951</a> <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>but as per Cisco document below they says that it is the best choice for firmware upgrade…I just remember a limitation of the number of phones that can connect to a root phone at a time and that was a silly limitation but I cannot find any document right not that talks about this number;
