[OpenSIPS-Devel] Reply INVITE

[Bogdan-Andrei Iancu]

Hi ,

Maybe you deal with INVITE retransmissions and your script gets also 
triggered for the retransmissions.

Try placing a t_newtran() (actually switching in stateful mode and 
absorbing eventual retransmissions) first thing in the "if INVITE" block
