UCM6202 call forward does not hangup


Hi I have an UCM6202 With analog external lines connected. When I forward to a cellular, the call remains active and doesnt hangup. When I end the connection manually works perfect. Have you any ideas?


you have to set the FXO tones and impedances correctly, you can do it manually or follow the automatic procedures (I prefer semi-automatic) that put you inside the analog trunk and on the system HW


Hello … as @damiano70 has stated this is a tones issue on the fxo ports not being set correctly… the one you need to look at is the busy tone detection…
