Troubleshooting the Polycom CX700 Phone
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.
