Hi,

my kamailio server is receiving from some customers 3 identical INVITEs when call is initiated (separated by 200ms). Those 3 INVITEs are making a big problem with call_control:

WARNING: call_control [call_control.c:1156]: dialog to trace controlled call was not created. discarding callcontrol. 

That is why, the prepaid limit is not working at all in this case. This way the user can hack the prepaid protection of the account. Otherwise the call_control is fuilly functional.

Anybody experienced the similar problem? If so, how to resolve it? 

Thanks,
Mino Haluz
