Todo:

It would be nice to be able to redirect 2 channels at the same time like you can with AMI redirect. However, it is not possible to acquire two channels without the potential for a deadlock with how ast_channel structs are managed today. Once ast_channel is a refcounted object, this command will be able to support that.
