While I disagree that it makes it "very hard to understand" I will say 
that it could potentially be improved. I dislike "call_dialog" because 
it sounds limiting. "Calls" are all about phones, and we don't want our 
API to sound like it's limited just to phone use. We're less focused on 
setting up calls than we are about setting up media sessions.

In general, the use of the word "session" is mostly used correctly with 
regards to the API. It could only arguably be changed for API calls like 
the one you pointed out where the word "session" used on its own might 
cause someone to do a double-take to realize what is meant. I propose 
simply adding the word "dialog" to the API calls to make it more clear. 
That would mean that


would be changed to


This way the "ast_sip_session" prefix remains so that it's clear what 
resource module is providing the API call, but it also is more clear 
that the reinvite, response, or request is being sent on the dialog that 
the session belongs to.

What do you think of that?
