[Serusers] BYE method not handled properly

I would like to know why does my BYE method are always replied with a
'Call Leg/Transaction does not exist' . How do they compare whether the
transaction in the BYE method exist or not ? ( tag? ftag ? ) Are there
any thing in the config that might cause this kind of problem ? Just
want to highlight that all the calls are made in a good condition,
everything except when the call is ending. I have checked that the
phones have not received a prior BYE. Any other idea what is wrong ?
 
Here's a more detailed situation :-
 
Caller (PSTN) --> Voice Gateway --> OPENSER --> Callee (UA)
 
When Callee (UA) tried to end the call , OPENSER will forward a copy of
the BYE to Voice Gateway to inform him of the BYE.
 
The Gateway , somehow , replied with a 'Call Leg/Transaction Does Not
Exist' . The strange thing is, the Caller (PSTN) was somehow informed of
the BYE method and terminate the session . Anyone has any idea how to
handle these errors ? I will be glad to provide a ngrep for more
reference.
 
Please let me know if you dont understand.
 
Regards,
Sam
