[Asterisk-Dev] Problem with hanging up a SIP channel

[imran ahmed]

I think I forgot to add this:
You are not allowed to call ast_hangup from within an application on a
channel you havent created.
But if the channel was created inside the application such as app_dial
then it should be hungup inside app_dial using ast_hangup and not
ast_softhangup. ast_softhangup is only suitable to hangup a channel
asynchronously from some other thread (which infact doesnt hangup the
channel but only sets up a flag that the channel needs to be hungup),
and ultimately ast_hangup has to be called to complete terminate a
channel.
