Troubleshooting the Polycom CX700 Phone
41
To confirm the Polycom CX700 phone can locate / run ucdevice.upx (which in
turn locates the correct CPE.NBT file):
>> Use a browser to confirm you can access the virtual directory where the
ucdevice.upx file is located:
Internal
http://pool01.contoso.com/RequestHandler/ucdevice.upx When
hitting this link, an XML file showing the current firmware version
will be displayed if security is set properly.
External
http://ocsrp.fabrikam.com/RequestHandlerExt/ucdevice.upx
When hitting this link, an XML file showing the current software
release will be displayed if security is set properly and the reverse
proxy publishing rules map the reverse proxy FQDN to the
/RequestHandlerExt virtual directory on the pool hosting the Device
Update service.
To confirm that the Polycom CX700 phone can get to the device update files,
the following example provides instructions for a Polycom CX700 running
build 199 with planned upgrade to build 522:
Internal (assumes pool running Device Update service =
pool01.contoso.com)
http://pool01.contoso.com/DeviceUpdateFiles_Int/UCPhone/Poly
com/CX700/A/ENU/1.0.522.101/CPE/CPE.nbt When hitting this
link, you should get prompted to save cpe.nbt if security is set
properly.
External (assumes reverse proxy FQDN = ocsrp.fabrikam.com)
https://ocsrp.fabrikam.com/DeviceUpdateFiles_Ext/UCPhone/Pol
ycom/CX700/A/ENU/1.0.522.101/CPE/CPE.nbt When hitting this
link, you should get prompted to save cpe.nbt if security is set
properly and the reverse proxy publishing rules map the reverse
proxy FQDN to the /DeviceUpdateFiles_Ext virtual directory on the
pool hosting the Device Update service.
When to Use DHCP Option 119
