I have accidentally upgraded the firmware of my device and now need to downgrade to ensure compatibility with my CudaTel PBX.

I need version

Is it possible to obtain this and is it possible to downgrade without causing any issues with base station or handset?

thanks for you information , but it is not recommended , as the newest firmware can also work with CudaTel PBX, and is really an old firmware and downgrade will cause some unpredictable risks
