Set up call
If the ME is on a call when the command ‘Set up Call’, ‘putting all other calls on hold' is sent, the user will see the text 'Setting up a call current call will be held'. If ‘OK’ is pressed the current call will be put on hold and the new call set up. If the ME is on a call when the command ‘Set Up Call, discon- necting all other calls’ is sent, the user will see the text ‘Setting up a call current call will be discon- nected’.

If no alpha identifier is supplied and several items are found in the menu, a default title is used. If the SIM AT Menu Item is selected by pressing ‘Select’ all the items sent in the Set Up Menu command will be available for selection, in the same way as the Select Item command.
