[Kamailio-Users] Checking the destination IP after dispatcher

What pseudo variable would i check after running ds_next_dst() to check the IP we are about to forward the INVITE to? Basically I want to have a check for $si == [something] to ensure I am not about to send the INVITE to the same UI which just requested it. While I have your attention, I may as well see if anyone has a better solution for what I am trying to accomplish: I am doing this because asterisk can't handle a hairpin scenario and I need to generate two distinct calls in my network, so I figure i'll just forward the request to another server in the network to deal with this. INVITE from PSTN --> Kamailio --> Asterisk#1 [Asterisk#1 needs to create a new session, but stay on-net] --> INVITE from Asterisk#1 to Kamailio --> [Dispatcher] --> INVITE from Kamailio to Asterisk#2 This would basically create 3 legs of the call, which is what I want PSTN --> Asterisk#1 --> Asterisk#2 I would prefer if Asterisk#1 could just INVITE to LocalHost, but that doesn't seem to be allowed. Not sure if that's a limitation of SIP or Asterisk... Thanks!
