Installed 2 x G450 HW3 delivered with stock firmware 36.8.0. Uploaded announcement files to the Gateways. Both gateways are working fine including announcements. When downgrading the G450 to the last available firmware 30.29.0 offical supported by CM5.2.1 the gateway itself is still working, but the announcement is not being played. The call is being dropped when calling the announcement directly.
With FW 30.29.0 it shows "Unknown VoiP DSP Module" in Slot 1 under "show system" which probably is the reason why announcement is not working.
After switching back to FW 36.8.0 the announcements are working again and the DSP is detected correctly.
