End-of-service Poly deskphones and devices
The following Poly phones are approaching their security certificate expiration date. We recommend upgrading to one of the supported replacement models listed to ensure continued compatibility and security updates with AT&T Office@Hand.
Poly deskphones do not have a standard end-of-service date. Each device includes a unique security certificate (TLS) installed during manufacturing, which is tied to the phone’s MAC address.
Note
- Expiration date: When the security certificate expires, the phone can no longer connect securely to the AT&T Office@Hand system. Because expiration dates vary by device, please check the label on the back of your phone to find its security certificate expiration date.
- Special offers: Purchase five or more qualifying Poly phone products and earn up to $75 per unit with the HP Poly Phone Cashback Program.

Frequently asked questions
What will happen to my Cisco device when the security certificate expires?
Cisco has announced end-of-sale and end-of-life dates for Cisco SPA 303 and other series model phones.
This means that your Cisco phone configuration will become locked when the security certificate expires. The phone will continue to operate, but configuration changes will not function normally. The devices will no longer be able to authenticate with the provisioning server so updates will no longer be possible. If the device is factory reset or if the phone configuration in the Admin Portal is deleted, the phone will stop working.

What should I do?
Customers should make plans to migrate from impacted Cisco devices to prevent business disruption.
Can I use a phone that isn’t on the replacement recommendation list?
The device can be registered as a BYOD phone by following the instructions for SIP manual provisioning.
What happens to my device after the security certificate expires?
Phones registered prior to the security certificate expiration will keep their connection, but if the phone is reset or unplugged it will not reconnect. If the connection is lost, you’ll need to re-configure the phone as a BYOD device by following the instructions for SIP manual provisioning.
What if I need additional support?
You can contact your Service Provider for support or reach out to your account representative.
