Hi List

To correctly route ACK belonging to a transaction (totag) the example code does:

if ( is_method("ACK") ) { if ( t_check_trans() ) { route(RELAY); exit; } else { xlog("L_INFO", "$cfg(route): $rm NOT loose route NO transaction found DROP\n"); exit; } }

Unfortunatels I fear that in a parallell forking scenario, the transaction is remove from memory as soon as the first 'negative' ACK is being processed so that the end 2 end ACK to the 200 OK of the branch that connected the call, never makes it through.

I attempted to increase wt_timer to 10000 to have the transaction stay around 10 seconds but that does not solve the issue.

I read that t_check_trans()'s result shall be considered more as a hint than as a confirmation of an existing transaction.

Is there a clean / secure way to process e2e ACK and make sure they belong to a transaction? Or can I just safely remove the t_check_trans() call and route any ACK with a totag?
