[Bogdan-Andrei Iancu]

Hi Juha,

the MI stuff does not affect at all the syntax of TM functions 
t_write_unix() and t_write_req(). These are inside2outside functions 
used for pushing data from openser to an external application (via 
unixsock or fifo).

MI in only for outside2inside functions - internal functions triggered 
by external applications. MI is an internal interface in order to have 
only on internal implementation of the functions, totally independent of 
the transport mechanism (fifo, unixsocks, etc).

So, for SEMS point of view, the affected ones will be the internal 
functions exported by TM:
    t_uac_dlg
    t_uac_cancel
    t_hash
    t_reply

I guess all are used by SEMS excepting t_hash function.

So, to answer to your question, yes, in the MI implementation (via fifo 
and XMLRPC and future unixsock - still in progress) the syntax was 
changed a bit (for consistency and clarity reasons) for both t_uac_dlg 
and t_reply.

the changes are here:

  Syntax of "t_uac_dlg" (as lines):

	(old version)			(new version)	
	method				method
	RURI				RURI
	NEXT_HOP?|socket?		NEXT_HOP?
	new_headers*			socket?
	\n				new_headers?
        Body*				[Body]
	.


   Syntax of "t_reply" :

	(old version)			(new version)
	code				code
	reason				reason
	trans_id			trans_id
	to_tag				to_tag
	new headers*			new_headers?
	\n				[Body]
	Body*
	.

  Legend:
	* can be multiple lines
	? if empty value, the line contains only the '.' char
	[] can completely miss
	in new version, for multiple lines values (like new_headers and body) a quoted string can be used (inline '"' must be escaped)


I will try to upload all this on a wiki, or better to doc the MI 
functions in the module's readme

regards,
bogdan
