[Derrick Ding]

Hi,

Thanks for your reply,
I solve this issue by modifying tm/config.c

Line 69: change 1 to 0.

this works for t_realy_to() indeed, for other functions, there is either

a module parameter to set this kind of behaviour globally or a function 
to do it per transaction:
http://kamailio.org/docs/modules/stable/modules/tm.html#auto_inv_100
http://kamailio.org/docs/modules/stable/modules/tm.html#t_set_auto_inv_1
00

These are valid in v3.x.

Cheers,
Daniel
