Method Detail

connect

public void connect()
             throws AccessControlException

Connect the call.
For incoming calls, accept the call and put the call in ConnectionIF.CONNECTED state.
For outgoing call, try to establish the call (for ISUP, send the IAM).

Throws:

AccessControlException - if requested operation fails.

receive

public void receive()
             throws AccessControlException

For incoming calls, send backward ack

Throws:

AccessControlException

disconnect

public void disconnect()
                throws AccessControlException

Disconnect the call. A release must be sent to the distant and the ConnectionListener need to be called as listener.connectionStateChange(ConnectionIF.DISCONNECTED) when the call is really released

Throws:

AccessControlException - if requested operation fails.

getCalledAddress

public Address getCalledAddress()
                         throws AccessControlException

Return the called address

Throws:

AccessControlException

getCallerAddress

public Address getCallerAddress()
                         throws AccessControlException

Return the caller address

Throws:

AccessControlException

getCallSpec

public CallSpec getCallSpec()
                     throws AccessControlException

Throws:

AccessControlException
