# Known issues 8.4

We have identified the following known issues in 8.4. Look for resolutions for these issues in the upcoming releases:

| Issue | Comment |
| --- | --- |
| **Agent-to-Agent Dialing** | The new and improved methods of **agent-to-agent** dialing are not implemented in this release. Dialing the extension number from the shared directory and from the telephone field in the **Control Panel** will be supported in the upcoming release. We continue to support **agent-to-agent** dialing via the **Agents** tab in the **Control Panel**. |
| **Agent DID Call Routing** | Incoming calls for agent PBX number and DID number always get mapped to the IVR script assigned to the PBX number. If you have specified separate treatments for customer-to-agent dialing and **agent-to-agent** dialing, the PBX number script overrides the existing DID number script. |
| **Warning for Emergency Calling** | **8x8 Contact Center** dedicated extensions do not allow outbound calling and hence do not support calling the emergency services. On going off-hook, these devices currently do not hot dial to a warning message. |

> [!NOTE]
> Note:
> 
> Please notify agents using dedicated extensions that emergency calling is not supported on these devices.
