Outbound flow failure handling merged to master

by Hugh Waite

Hello, As you will see I have merged my branch back into master. These changes add a new event route [tm:branch-failure] to the tm module which is run when any failure response is received on a transaction. The event_route uses a new route type BRANCH_ROUTE which limits the functions that can be run in the route. The functions t_check_status(), t_next_contact_flow(), t_relay() and unregister() can be used in this route. A new pv $T_reply_ruid is accessible in this route which can be used to unregister a single contact entry. The following example route can be used on a registrar to handle failed or invalid flows: event_route[tm:branch-failure] { xlog("L_INFO", "event_route[tm:branch-failure]\n"); if (t_check_status("430|403")) { if (!unregister("location", "$tu", "$T_reply_ruid")) { xlog("L_WARN", "failed to unregister $tu with ruid $T_reply_ruid\n"); } if (!t_next_contact_flow()) { xlog("L_INFO", "No more flows\n"); } else { xlog("L_INFO", "Next flow\n"); t_relay(); } } } Any bugs, memory leaks etc. let me know!

Using t_suspend()/t_continue() multiple times on the same transaction

by Peter Dunkley

Hi, I am trying to use t_suspend()/t_continue() multiple times on the same transaction. Calling t_suspend() more than once works, but the second time I call t_continue() the transaction is killed and a 500 response is sent. It is the "if (branch == t->nr_of_outgoings)" check from the code fragment below (from t_suspend.c:t_continue()) that results in the transaction being killed - you can see the debug/error line I added to determine this in the fragment. Is using t_suspend()/t_continue() multiple times something that should work? Thanks, Peter if (t->uas.status < 200) { /* No final reply has been sent yet. * Check whether or not there is any pending branch. */ for ( branch = 0; branch < t->nr_of_outgoings; branch++ ) { if ((t->uac[branch].request.buffer != NULL) && (t->uac[branch].last_received < 200) ) break; } if (branch == t->nr_of_outgoings) { /* There is not any open branch so there is * no chance that a final response will be received. */ ret = 0; LM_ERR("branch == t->nr_of_outgoings\n"); goto kill_trans; } } -- Peter Dunkley Technical Director Crocodile RCS Ltd

default config: do loose_route() for in-dialog NOTIFY as per new RFC 6665

by Iñaki Baz Castillo

Hi, the new RFC 6665 mandates that the subscription dialog is made *after* the first NOTIFY from the UAS (rather than after the 200 to the initial SUBSCRIBE). This means that the UAC MUST take the route set from the *first* received NOTIFY (instead of taking it from the 200 to the initial SUBSCRIBE). Therefore a proxy compliant with RFC 6665 MUST always add RR to in-dialog NOTIFY requests and thus, I propose that the default SR script file implements it. Regards. -- Iñaki Baz Castillo <ibc(a)aliax.net>

json and jsonrpc-c modules

by Matthew Williams

Hi, The Flowroute development team is pleased to announce a complete overhaul of the json and jsonrpc-c modules, originally authored two years ago. Credit should first and foremost go to Joe Hillenbrand who did most of the new development. Jordan Levy (our CTO) and I were also involved in the updates and QA to a lesser extent. The updated modules are available in the mgw/json branch. In addition to the Kamailio modules, we have developed a Twisted Python library to complement the jsonrpc-c module: https://github.com/flowroute/txjason We would be interested in any critiques of the API, documentation, and code. Please let us know if you use these modules and especially if you find any bugs. We hope to merge this into master once we have had it in production for awhile and (ideally) have received some feedback from other users. Feel free to contact either Joe (joe(a)flowroute.com) or me directly with any questions or comments. -- Matthew Williams Flowroute LLC http://www.flowroute.com/
