FYI, I just updated UCS firmware from 5.8.2 to 5.9.0 and noticed that I am not able to set EHS mode to Plantronics. Comparing UCS Admin Guide, 5.8.1 and 5.9.0, I noticed the default up.analogHeadsetOption value is changed from No EHS-compatible headset is attached to Plantronics EHS-compatible headset is attached.
With 5.8.1, reboot is not required, but 5.9.0 is. Interesting thing is the phone with UCS 5.9.0 default is "No EHS-compatible hedset is attached" setting, not Plantronics EHS, and if I select Plantronics, the phone reboots, but it set back to "No EHS ~" setting after reboot.
Just curious whether this is known issue or not.
At this moment, I rolled back UCS firmware to 188.8.131.5232 and the headset setting works flawlessly.
- UCS Admin Guide: 5.8.1
- UCS Admin Guide: 5.9.0
Solved! Go to Solution.
I don't see this issue here but curious of a few things:
Was the phone fully configured with desired configuration before the upgrade to 5.9.0? Or was the upgrade done and then the configuration was applied (and caused the failure)? If the phone is on 5.9.0 and reset to default, then all the same config applied, does the issue still happen?
Thanks for your time.
Thanks for your reply. I noticed the setting properly remained once I factory resetted the phone manually. I confirmed Plantronics EHS setting was the default setting and select it explicitly with up.analogHeadsetOption="2" in my provisioning file.
The issue is likely that you have the serial port enabled. To use EHS you'll need to disable the serial port on 5.9.0. We changed this for an intermittent issue we found internally.
To resolve you should make sure to disable the serial port.
We'll sort out the knowledgebase to better clarify this. Since customers don't typically use the UART on the serial port so disabling it should have no negative impact.
Once again thank for sharing the knowledge!
In my provisioning file, I see "device.set="1" but neither "device.serial.enable.set" nor "device.serial.enable" are defined, I am assumning I should explicitly define them to prevent EHS issue?
Also I noticed that Acoustic fence feature can co-exsist with EHS setting with 5.9.0, I am happy for that. (I used to have looping issue with previous release)
"I am assumning I should explicitly define them to prevent EHS issue?"
You can do this to prevent the issue yes but ultimately you shouldn't need to do this. The parameter may have been in config at some point previously and never disabled/removed. The factory reset removed it. Either way disabling will prevent the issue from showing up again and will keep you from having to factory reset any other phones.
I have a VVX411 running 5.5.2, and I recently purchased a Plantronics CS540 with an APP-51 EHS.
After connecting everything, and changing the hookswitch mode from "Regular" to "Plantronics EHS", the phone reboots and after rebooting, the system reverts back to "Regular".
Any help is appreicated.
Hello @bduncan ,
welcome to the Polycom Community.
Both the community's Must Read First and the community's FAQ reference the basic minimum information a new or follow up post should contain.
As you have not attached any kind of log or a backup we can only assume that the issue is caused by a configuration being used.
The suggested configuration was already provided and I attached a file which you should be import using the Web Intereface:
Utilities > Import & Export Configuration > Import Configuration
In addition UC Software 5.5.2 is no longer a supported version so please upgrade to something more current like UC Software 5.9.1
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
