[Serusers] acc problem

[Jiri Kuthan]

That is because you don't use Record-route. You have to use
it in order to enforce reouting of subsequent requests 
through SER. Otherwise, they are routed directly between
end-devices, that's how SIP works. The missing script
action is bellow, I will document this issue in user's
guide.
