I briefly glanced at the code before responding, and it does seem that if you specify a bind address it will use that address when responding. I stick by my comment that the change you want is not exactly simple - unless you are very familiar with the 18,000 line chan_sip.c :) It also appears that the bind address is a global in this implementation... so some thought would have to go into efficiently representing all the possible peer bind addresses in a thread safe manner... and if the change is made to this channel it really out to be for all of them.
So a "hack" is probably possible without too much trouble. For it to be done right is not a simple change.
