Hello, two of the last three modules that were not ported to use the new sip router core are ready now: nat_traversal and siptrace. Particularly, siptrace was refurbished, should catch now forwarded ACK. Before release, there are couple of new features that should get in trunk since sip route core offers support for such extensions: - ability to filter the ACK for negative replies issued by sl module in the script - ability to store stateless forwarded messages (now only stateful ones being stored) Testing is very much appreciated.
