Thanks for your recommend.
We are using the T200=300ms corresponds to Abis terrestrial link. (in Alcatel have only 2 choices, Terrestrial=300ms and Satellite=1000ms.)
More information and more question about this problem.
We found the time after the CLUPD(send from BSC to MSC) before the CLCMD(send from the MSC to the BSC has the cause value=call control) is equal about 11s.
From this it look like the time out behavier.
Could anyone please tell me that which timer should it be?
