>          Issue Type: Bug
>      Security Level: None
>          Components: Channels/chan_dahdi
>    Affects Versions: 1.8.23.1, 11.5.1
>            Reporter: Tzafrir Cohen
>            Severity: Minor
>         Attachments: dahdi-devstate-cachbility-workaround.patch

> To reproduce:
> Setup: A DAHDI extension that can call to a SIP extension and to at least any other exteension (may be anything).
> To reproduce:
> 1. Run 'event dump cache DeviceState' to see DAHDI device is not there.
> 2. From the DAHDI extension dial to the SIP extension.
> 3. In the DAHDI extension press flash for an attended transfer.
> 4. Dial the other extension number and hang up.
> 5. In the CLI, run 'event dump cache DeviceState'. You'll see the DADHI device listed as 2 (in use).
> Expected results: in stage 5, the state of the DAHDI device should not have appeared in the cache, or listed as "unknown".
> See also the similar ASTERISK-22718
> A workaround patch is attached, to forcefully disable caching of DAHDI devices.
> Marked as regression as it has worked OK up until 1.8.19. Broken in 1.8.20.
