Hello,

ok. I am cc-ing to mailing list to close the discussion thread. The issue was actually caused by a mis-configuration.

Cheers, Daniel

thank you a lot, I will do it and let you know question: if the call is not cancelled, after the 200 OK there is an ACK, why that ACK does not have any prob?

thank you a lot, I am attaching the config file

in the main route block you have nothing that process the ack, so it gets drop.

Try to add:

      if ( is_method("ACK") ) {
          if ( t_check_trans() ) {
              t_relay();
              exit;
          } else {
              exit;
          }
      }
