The recent firmware and Teams updates applied to our Audiocodes C435HD handsets has broken the Hotline feature. This is causing significant issues as our help phones are no longer auto-dialling. Is there a way to downgrade these devices to the previous versions?

    Hello Stewart Ross1,

    Thank you for reaching out to the Microsoft community.

    Based on the information you provided, I have consulted with a member of my team about your situation, and I would like to share some more specific directions with you.

    Microsoft's back-end support team should collect advanced log information from Office 365 Global Admin personnel through a remote session to diagnose the current scenario. If needed, a front-line technical support engineer can also involve a specialized support team to investigate further.

    Due to the limited permissions and access resources of our forum moderators, we cannot collect certain types of log information in public forums to ensure user data privacy.

    After diagnosing the situation, our technical support team will provide possible solutions from their perspective. If there are any known issues, the Technical Support Engineer can share this information based on their back-end resources.

    Office 365 Global Admins in your organization may need to contact the Office 365 support team through an open service request to diagnose this particular scenario with more technical resources.

    For standard procedures, Global Admins can refer to the official documentation: Get support - Microsoft 365 Admin | Microsoft Learn.

    You can also call Microsoft support via- https://support.microsoft.com/en-us/topic/global-customer-service-phone-numbers-c0389ade-5640-e588-8b0e-28de8afeb3f2 Note: If you are an end-user person, you may need to contact the Office 365 Global Administrator in your business organization to contact a Technical Support Engineer for further processing.Important: If any of your organization's Office 365 Business/Business/Education subscriptions are from a federated partner or reseller and the global admin can't open a service request on their end, they may need to contact the reseller's support provider so they can help the global admin open the service request on their end. After that, the Office 365 support team will participate in the service request that was created.Thank you very much for your valuable time in your cooperation.
