[FAQ] I get the error Message “Could not contact boot server” on my phones screen

A Polycom Phone usually checks on booting up for it's Software and Configuration that is commonly installed on a => Provisioning Server <=


Before the Introduction of UC Software 3.3.0 the phones depended heavily on the fact that they could reach this => Provisioning Server <=


If a phone had been reset to factory default the phone would need to load the SIP Software again in order to function.


NOTE: If no Provisioning Server is provided the phone will continue to reboot in a cycle!!!


A phone usually receives its => Provisioning Server <= IP address or host name via a DHCP Server in a private network.


NOTE: Polycom changes the Factory Settings and notifies customers of these within the Notice of Product Shipping Configuration Change that can be found => here <=


A DHCP request would query DHCP Option 160 (Customer) and also Option 66




If no such DHCP Option exists or a public network is used the setting must be changed to static in order to manually identify the location of an => Provisioning Server <=


Please ensure on Boot Up to press the Setup Soft Button and then add the Standard Polycom Password of 456.


You can check the DHCP Menu to verify if Custom+Opt.66, Option 66, Custom or Static is set as the Boot Server Address.


If set to Static the next step is to leave this menu and check the Server Menu for the IP Address/Hostname of a HTTP(S), FTP(S) or TFTP Server in order to identify the location of an => Provisioning Server <=




NOTE: Depending on the Software Version on your Phone the menu layout may be different!


You may need to liaise with your Network Administrator to confirm the DHCP Options or if the Phone can reach the Provisioning Servers  IP Address/Hostname.


If the Phone is unable to reach this Server it will keep rebooting until it is able to do so.
