Reply To: Dropped Call


Hi Herry
As per 3GPP 24.008,This cause indicates that the network is not functioning correctly and that the condition is no likely to last a long period of time; e.g., the user may wish to try another call attempt almost immediately.

This means that there is a temporary failure at the physical layer of the network.So,you need to check all possible resons.You can start like this

If few cells,check for HW alarms,Tx media etc

If occurs randomly in almost every cell,check for TXCDR pool mismatch,Equipment failure,etc etc.
