[Users] maddr parameter

[Watkins, Bradley]

I see that there was some discussion back in March 2006
(http://www.openser.org/pipermail/users/2006-March/003339.html)
regarding this parameter, but nothing since.  Daniel mentioned that
perhaps it might be put on the to-do list, but I see no mention of it
anywhere else.  Was this implemented in 1.2?

I see that maddr is available using pseudo-var transformations as
{uri.maddr} in 1.2, but not mention of any automatic behavior if the
parameter exists.

I realize that I can work around it by using subst and subst_uri, but I
really shouldn't have to.  A simple t_relay should send it on its merry
way to the value of maddr.  My reading of both RFC3261 and 3263 seem to
imply that the existence of this parameter in the request URI mandates
forwarding the request to this address.  

I see in the code (for 1.1.1, I haven't looked at 1.2 yet) that the
parameter is parsed, but then it appears (correct me if I'm wrong) as
though nothing further is done with it.  Is there some relatively simple
way to modify the code to so that the maddr is used directly?

As you can probably tell, I have a gateway with which I have to
interoperate which uses this parameter extensively, hence my interest.
:)

Any advice (even if it's "use subst and subst_uri you whiner" ;) ) is
appreciated.

Thanks in advance,
- Brad
