We have 5 Polycom Soundpoint 6000s (in addition to 50+ 550 desk phones). 2 of the 6000's work fine, booting from our Trixbox server with no issue. 3 of the 6000's however fail trying to get boot parameters via dhcp. I have reset to factory defaults, verified the phone settings to match the working phones and verified the dhcp.conf file on the server has the same format for all phones. I have used the same cables from the working phones and still have the same behavior. I am out of things to check. Any advice would be appreciated.
welcome to the Polycom Community.
Please reboot the units in Question and press setup when the countdown appears.
Use 456 as the Password
Go to the DHCP Menu
Check that the Boot Server is set to Custom+Opt.66
Above will allow your DHCP Server to provide the Phone with the URL for your provisioning Server.
Compare this setting with your working Phones and ensure that the DHCP Scope for the Phones in Question is using the same settings as the working Units
I would recommend a Wireshark Trace as shown => here <=
Get your IT Team to set up a spanned/mirrored Port or use a Hub and capture the whole boot up process and get the IT Team to analyze the Trace in order to see if the Polycom Device is sending the DHCP request and is being assigned the options from your DHCP Server.
If above shows that the Phone is provisioned with the correct Information you may want to contact your Polycom Reseller as they can open a Service Ticket with Polycom Support
If official support is required please check how to phone or open a case here----------------
