We have been informed by Panasonic that phones manufactured in mid-2017 have a problem with the embedded client certificate.
Affected devices are all TGP600/HDV series manufactured from July to November 2017. The issue is that the certificate loaded into the device at the point of manufacture only lasts for one year instead of the usual thirty. This affects provisioning systems which secure connections by validating a device’s client certificate. As a result of this, at some point in July 2018, these devices will start to fail to provision if client verification is being used.
The fix is to upgrade the firmware of the device to the following versions (or newer):

For customers using our provisioning platform, please contact us to organise upgrades of your phones. We can handle this automatically for you, but will require your consent to do so – phones will not be automatically upgraded.
For customers using other provisioning systems, please get in touch with whoever manages the system to organise the upgrades. If they require assistance, we are happy to help.
Panasonic has also provided a website for checking your phones.
We would like to apologise on behalf of Panasonic for any inconvenience this may cause. If you have any questions, please don’t hesitate to get in touch, you can call us on 01484 840048 or email firstname.lastname@example.org.
