CCX 700
Poly

New Features:

Enhancements:

Nothing known

Fixed Bugs:

Calling - On CCX 500 phones with the Microsoft Teams base profile, the first outgoing call after reboot doesn't play a ringback tone until after the call connects. All subsequent calls work as expected.
Configuration - Auto off hook number doesn't take effect unless manually rebooted.
Configuration - Poly CCX phones with an unreachable provisioning server address may enter a reboot loop due to core file upload crashes.
Networking - Failure to parse SCEP requests using indefinite-length BER encoding in PKCS#7 payloads.
Provisioning - Phone fails to establish HTTPS connection with the ZTP server at startup.

Open Issues:

User Interface - CCX phones using the Genband GlobalAddress Book (GAB) clip the display of the Submit and View softkeys.
Interoperability - Poly Lens dashboards show the private IP of a CCX phone as "unknown".
User Interface - A small icon on the CCX active call screen may be delayed in updating from the active call icon to the hold icon when a call is on hold.
Audio - Bluetooth connected Poly Voyager Focus set (B825) may experience brief audio disruption on the first call after a reboot.
Provisioning - Poly CCX phones with an unreachable provisioning server address may enter a reboot loop if the phone crashes during core file uploads (Workaround: Use the Web Configuration interface or the phone menu to correct/delete the provisioning server address).
Hardware - Specific user events do not extend the phone lock feature's user input expiry timer, causing the phone to lock during menu navigation (Unlock the phone as normal to continue using the menu).
Diagnostics - The trace route diagnostic tool from Settings > Diagnostics > Network does not return any results.
Networks - The Poly web proxy code cannot process PAC files with FQDNs containing the characters Y or Z, resulting in failed Teams authentication.
