Re: [SR-Users] How to Absorb First Leg Re-Invites when no Response from Second Leg Invites

Hi, In addition , there is a function in tm that helps to understand branch timeout reason https://www.kamailio.org/docs/modules/5.1.x/modules/tm.html#tm.f.t_branch_r… Yasin Caner Alex Balashov <abalashov@evaristesys.com<mailto:abalashov@evaristesys.com>> şunları yazdı (2 Mar 2019 02:23): Hi, Reinvites are in-dialog requests; they would only be sent within the context of an established dialog (2xx response, end-to-end ACK, the whole works). Perhaps what you are referring to is not reinvites but retransmissions of the initial INVITE? If so, have a look at this option: https://kamailio.org/docs/modules/5.2.x/modules/tm.html#tm.p.cancel_b_method in concert with something like this: failure_route[...] { if(t_is_canceled()) exit; # The scenario you're after. if(t_branch_timeout()) { t_reply("503", "Service Unavailable"); exit; } } -- Alex On Fri, Mar 01, 2019 at 08:23:11AM -0600, JR Richardson wrote: Hi All, My mind is not right on this one, need a pointer. Here is the simple scenario: Carrier><kamailio proxy><end device The end device is a static IP, the proxy dips database and knows where to send numbers destined for the end device, but if there is no response from the end device (it's off-line), how do I time-out the transaction and send a 503 'Service Unavailable' back to the first leg for the carrier to stop re-invites? I assume I need a new [FAIL_TWO] route that handles this event. Thanks.
