[OpenSIPS-Users] more INVITEs

[Răzvan Crainea]

Hi, Dragomir!

You can detect retransmissions of the same message using the 
t_check_trans() function. But in order to use it properly, make sure you 
create the transaction as soon as possible.
A short snippet that could solve this is:

t_newtran();
t_check_status();

For more information please consult the documentation:
https://opensips.org/html/docs/modules/2.4.x/tm.html#func_t_newtran

Best regards,
Răzvan
