Busy tone not stopping after call ends

[Timur]

Hi all!
Can someone tell me how can I release the Line after one of the callers hang up?

For now it's -
1) Ext A talks to Ext B. (hands free mode)
2) Ext A hangs up.
3) Ext B hears Busy tone. ('TXX BUSY' on screen). And busy tone keep going untill timeout after 30 sec (Busy tone Timer I think).
Or I manually shut it down by pressing cancel or "hands free" button.

How can I achieve this?
1) Ext A talks to Ext B. (hands free)
2) Ext A hangs up.
3) Ext B hears Busy tone for 5-7 sec. and then releases the line. (Or release immediately)

I'm using MCD 6.0. Phones are Mitel 5340.
Can someone  please point me where to dig?


Thanks!

Cos option

Return Disconnect Tone When Far End Party Clear
 Was set to YES.
Changed to NO. Problem solved :-)
