[SR-Users] Branch feedback behaviour

Hello, I've got a situation like this: UAC ---> (Kamailio) ----------> 1. redirect server on branch 1 <---------- 2. 302 redirect ----------> 3. ACK ----------------------------> UAC B Problem is, if CANCEL comes in at the exact moment that the INVITE to the redirect server (#1) is "in flight", i.e. has not returned a 302 yet, then the transaction gets cancelled and 302 is fed back to the calling UAC. Having the 302 fed back to the calling UAC in any circumstances is quite undesirable. I just need to drop it. Problem is, in all other situations, I need to use it--I consume it in a failure_route and create new branches based on it. What's the best way to accomplish this? I'm concerned that if I use a global onreply_route to filter all 302s going back to callers, that will prevent it from percolating down to the failure_route. Suggestions appreciated, and thanks! -- Alex -- Alex Balashov - Principal Evariste Systems LLC Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/ Please be kind to the English language: http://www.entrepreneur.com/article/232906
