Sorry for the delay, but a had to wait for the customer to make a test call.
I placed a xlog("L_WARN", "has_totag after - M=$rm RURI=$ru F=$fu
T=$tu IP=$si ID=$ci\n"); just after the if (has_totag()) { .. } and it
does not show in the log.
It looks very strange to me. Do you have any ideas what is wrong.
