Hi Fred, Its more that the "user" on Kamailio is actually a PBX with extensions on it.
On asterisk I'd usually do Dial(SIP/peername/extension) but I obviously cant do this as Kamailio is the peer that the call is being routed to initially. What I need to figure out is how to on kamailo maybe using a dial prefix specify that the call is going to a remote extension on a "user" and rewrite the to header to be extension@useripaddress rather than user@useripaddress. Does this make sense?
