 The following example shows one way of accessing the channels that have hangup cause related information after a Dial has completed. In this particular example, a parallel dial occurs to both *SIP/foo* and *SIP/bar*. A hangup handler has been attached to the calling channel, which executes the subroutine at **handler,s,1** when the channel is hung up. This queries the HANGUPCAUSE\_KEYS function for the channels with hangup cause information and prints the information as a Verbose message. On the CLI, this would look something like:

 ### HANGUPCAUSE
 
 Used to obtain hangup cause information for a specific channel. For a given channel, there are two sources of hangup cause information:

 #### Example
 
 This example illustrates obtaining hangup cause information for a parallel dial to *SIP/foo* and *SIP/bar*. A hangup handler has been attached to the calling channel, which executes the subroutine at **handler,s,1** when the channel is hung up. This queries the hangup cause information using the HANGUPCAUSE\_KEYS function and the HANGUPCAUSE function. The channels returned from HANGUPCAUSE\_KEYS are parsed out, and each is queried for their hangup cause information. The technology specific cause code as well as the Asterisk cause code are printed to the CLI.

 ### HangupCauseClear
 
 Used to remove all hangup cause information currently stored.
 
 #### Example
 
 The following example clears the hangup cause information from the channel if *SIP/foo* fails to answer and execution continues in the dialplan. The hangup handler attached to the channel will thus only report the the name of the last channel dialled.
