Hello Nathaniel,
In script, for initial requests, you can use t_newtran() (very
aggressive approach) or t_check_tras() in order to detect
retransmissions. Do that before doing any other particular processing
for the INVITE (the idea is to detect the retransmission asap, before
doing anything else).
t_check_trans() checks if it is a retransmission (by looking into the
existing transactions in memory), but does not create a transaction if
not a retransmission - the transaction will be created later, by t_relay().
t_newtran() checks and create transaction if not retransmission.

Hello,
I have a couple of questions I would like to ask. First, I have a
client that is sending the initial Invite twice and I would like to
know how to detect this within the script? The dual invites are
causing double accounting and other minor issue. Second, I have a
scenario where I have p1 send all registrations requests to p2 to
process requests. Registration of user is successful, but when you try
and call the user, opensips can not complete the call even though the
user is found in the location table. How can I resolve this. Also, the
user is behind a NAT.
Thanks
