I am having some trouble getting Siremis 4.0 to work with Kamailio 4.0.  The PHP application is functioning fine and all the DB access is working as intended.  Where I am having an issue is with the "Command Services" section.  I am unclear weather I want the "MI" or "XMLRPC".  The basic functions I want to use would be:

sip_trace on/off
debug XXXX
lcr_reload
address_reload

I know they are going to be different coming from 1.5 to 4.0, but I am hoping there is still a way to get Siremis to invoke these commands.  When I click on the XMLRPC section, I get this error:
