[kamailio/kamailio] Option to not add received via param (Issue #3515)
by zusrut 15 Apr '24

15 Apr '24

### Description Hello. Probably I'm doing something wrong but I can't get rid of **received** parameter in the **Via** header in responses from kamailio by websocket transport. According [RFC 7118](https://datatracker.ietf.org/doc/rfc7118/): `` When a SIP WebSocket Server receives a request, it MAY decide not to add a "received" parameter to the top Via header. Therefore, SIP WebSocket Clients MUST accept responses without such a parameter in the top Via header … [View More]

[kamailio/kamailio] branch_failure route in case 503 and dns failover (PR #3138)

#### Pre-Submission Checklist    - [ ] Commit message has the format required by CONTRIBUTING guide - [x] Commits are split per component (core, individual modules, libs, utils, ...) - [x] Each component has a single commit (if not, squash them into one commit) - [x] No commits to README files for modules (changes must be done to docbook files in `doc/` subfolder, the README file is autogenerated) #### Type Of Change - [x] Small bug fix (non-breaking change which fixes an issue) - [ ] New feature (non-breaking change which adds new functionality) - [ ] Breaking change (fix or feature that would change existing functionality) #### Checklist:  - [ ] PR should be backported to stable branches - [x] Tested changes locally - [ ] Related to issue #XXXX (replace XXXX with an open issue number) #### Description  When we use DNS failover in case of timeout kamailio executes the branch_failure route. In the case of the 503 - on_reply route. This commit is to equate behavior in both cases. So if there are more candidates we will always execute branch_failure route and on_reply route only if this is the last candidate.

[kamailio/kamailio] topos module breaks UPDATE (Issue #3437)
by Guybrush T. 27 Mar '24

27 Mar '24

### Description Kamailio v5.5.6 with topos module and postgres DB. UAC (A) -> Kamailio Registrar (B) -> Kamailio PSTN GW (C) -> PSTN (D) Call goes from A to D, PSTN sends UPDATE, UPDATE is routed from C to A instead to B and then to A. #### Reproduction Caller calls callee and receives an UPDATE from callee. In my case it was when the call was routed to voicemail. #### Log Messages ``` Kamailio takes the wrong route in UPDATE (upstream) case.

[kamailio/kamailio] Library libjson-c-dev 0.15.2 not compatible with pua_json module (Issue #3376)
by Henning Westerholt 28 Feb '24

28 Feb '24

There seems to be an incompatibility in the pua_json module related to the libjson-c-dev" version. The module crashes on startup on version 0.15.2 (e.g. from Debian bullseye). It works with version 0.12 (e.g. Debian buster).

[kamailio/kamailio] callout from event_route [tm:local-response] only occurs once (Issue #3064)
by dpaape 03 Feb '24

03 Feb '24

version: kamailio 5.5.2 (arm6/linux) 55e232 raspberry pi 3b I initially stated that I was running on 5.5.3 but I was mistaken. However I checked the 5.5.3 source and it appears to be the same. I think that there is a bug in the tm module with respect to the "tm:local-response" event route. In the "t_reply.c" file, there is a static variable called '_tm_local_response_set_lookup'. This variable is initialized at load time to zero. It is checked in the '_reply_light()' routine and will … [View More]

[kamailio/kamailio] dialog: failover database loading behaviour in shared DB scenario, expiration of dialogs (#2080)
by Henning Westerholt 20 Jan '24

20 Jan '24

The dialog module will expire dialogs that don't actually belong to the particular proxy. Scenario: 2 proxies on 5.2.4 with a loadbalancer in front. Call was routed over proxy1, dialog timeout on proxy2 was shorter (to make it easier to reproduce it). The results: * Dialog synchronized with DMQ: proxy 2 would timeout the dialog * Dialog entry synchronized to proxy2 DB and proxy2 restarted: Proxy2 would timeout the dialog * Dialog entry synchronized to proxy2 DB and proxy2 not restarted: … [View More]
