412 Conditional request failed

by satyaprakash ch

Hi There were two PUBLISH requests were sent by the Kamailio Proxy server to the Kamailio Presence server. Processing of the first PUBLISH request resulted in the presentity table being updated - the "etag" changed from "a.1705053846.16611.21.1" to "a.1705053846.16613.23.2" Processing of the second PUBLISH failed because it also attempted to update the etag in the presentity table but at this point in time there was no match to the original etag value in the database Logs in kamailio.log: ------ ps_db_update_presentity(): No E-Tag match a.1705053846.16611.21.1 DEBUG: tm [t_reply.c:637]: _reply_light(): reply sent out - buf=0x7f81e5ca5fc0: SIP/2.0 412 Conditio... shmem=0x7f81de6da068: SIP/2.0 412 Conditional request failed. Will any one suggest how to resolve the issue of 412 conditional request failed.

How to assign xavp array to htable?

by Benoit Panizzon

Hi List Via sql_xquery I get a stacked xavp aka array. I would like to store that stacked xavp into a hash table for later usage in other transactions. Is this possible? Via xarp_parameters explode or implode does not work as that would stringy the same key multiple times.

How to set a branch specific variable?

by Benoit Panizzon

Hi Gang I would like to set a variable specific to the branch. Is there a way? append_branch($var(aor1)); $(branch(dst_uri)[-1]) = $var($dst1) $(branch(want_plus)[-1]) = 1; append_branch($var(aor2)); $(branch(dst_uri)[-1]) = $var($dst2) $(branch(want_plus)[-1]) = 0; t_on_branch("BR_T"); branch_route[BR_T] { if ($branch(want_plus)) { $rU = "+" + $rU; } } Or would there be a way to query the index of the added branch so I could stack an avp with that index to access in the branch route?

Re: STIR/SHAKEN

by Anthony Wittig

Hey everyone, I've set it up so that when the invite comes into Kamailio I suspend the transaction (save the transaction info in sht) and use dispatcher to send a request to our NSS server. On the reply from NSS I throw the identity header into a sht and continue the original transaction. Does that seem like the right way to do it? The next things I need to look at are: * if first NSS server doesn't respond quickly, try the second (change some timeouts and use dispatcher to try the backup) * if both NSS servers aren't working, I still want to resume the original call and let it through. Maybe I can keep track of the failures in a sht and if I have two failures, resume the original invite without the identity header.

by Anthony Wittig

Thanks! This is what I've got so far: 1. Kamailio invite -> NSS 2. NSS 302 -> Kamailio 3. Kamailio ack -> NSS I can see the identity header on the 302 response in my onreply_route. How can I replay the same invite from step #1 with the identity header I get back in step #2? Should I be doing something with a transaction on step #1, maybe start a branch that goes out to NSS and when it comes back resume the transaction (these are all words I've heard smart people say, but I don't fully understand them...).

by Anthony Wittig

Hello, We're attempting to add identities to our invites. I believe we want to send our invites to the NSS, and it'll reply with a 302'd invite with an identity header. We currently use FreeSWITCH for dialplans and media and Kamailio as our SBC. Should we be trying for something like: FreeSWITCH -> Kamailio -> NSS (302) -> Kamailio -> PSTN or would it make more sense to do: FreeSWITCH -> NSS (302) -> FreeSWITCH -> Kamailio -> PSTN Assuming we wanted Kamailio -> NSS, is using dispatcher the right approach? We currently use it for our two Kamailios and our FreeSWITCHs. We're going to have two NSS servers, one for failover. Any thoughts would be greatly appreciated, thanks! -- Anthony Wittig Mango Voice Developer

How to check for branches with a pending reply in MANAGE_REPLY to correctly handle rtpengine?

by Benoit Panizzon

Hi gang location database contains multiple contacts for an AOR The invite therefore is parallel branched to those multiple contacts. Each reply from each branch is handled by MANAGE_REPLY. rtpengine_manage() is called in MANAGE_REPLY to stop rtpengine processing a failed call. Unfortunately, if any of the contacts replies with an error rtpengine_manage() will stop RTP processing. Is there a way I could check if there are branches with a pending reply from within MANAGE_REPLY so I could call rtpengine_manage() only when the last reply (no pending replies) are present? Hmm, realizing, if I process the last pending error reply and a prior one got a positive reply, this would still kill media. => How do I solve this?
