yes, really, if you use the save() function with a single parameter
("location") and the max_contacts parameter, registration is only one AOR!
But if you try to use save("location","c($avp(maxaor))") restrictions on
the AOR is canceled (and used a string of the form:
"$avp(loadedip)=domain;$avp(subscriber_username)=username;$avp(maxaor)=maxaor")
This save function bug?
But I need some users to allocate more than 1 Number of AOR...
