> 
> This patch adds a channel callback function get_other_side() (I am totally open to another name for this) that given one side of a local channel, will pass back the other side. This is used in the func_channel_write function to apply any changes to both sides of the local channel.
> 
> There are other places in the code where we specifically check for a local channel and look up the other side of the channel via relying on the names of the channels being similar and doing an ast_get_channel_by_name_locked(), but that is just exceedingly gross. We can't use the get_base_channel() callback because that could have some unintended consequences during a masquerade.
> 
> I propose that we make this change in all supported release versions, despite it being an API change, since there really is no other way for a local (/n) channel in a queue to set the desired language without *some* kind of fix--and this is the least hacky way I could come up with.
