When I get a call forwarded to my cell (smartphone) phone, it either doesn't ring or rings once and I don't have time to answer it.
- Login in the PISTON interface as admin.
- Locate the callflow that your cell phone is assigned to, most likely your extension call flow.
- Open the user box in the call flow.
- Change the 'Ring this user's devices for ___ seconds' from 20 seconds to 45 seconds.
