HI,
can someone assit me for my problem, i use CO trunk connect to PSTN, the trunk can't release automatic, how can i detect busy tone disconnection so the trunk can release

There is never any disconnect supervision on loop start CO trunks. You do get disconnect supervision on ground start CO trunks.

Hi,

If we use trunk type : ground start, still have any parameter to configure busy supervison

Thanks
