[kamailio/kamailio] Expand the list of required default 3rd party libraries for Kamailio (#969)
by Olle E. Johansson 02 Dec '20

02 Dec '20

(from devmeeting #Fosdem) - adding new dependencies as core dependencies - Curl - libssl - uuid - libunistring - libxml2 Any other candidates? They have to be libraries that are commonly installed on most Linux/Unix system. This would mean that a lot of more modules will be built by default, like TLS, HTTP_CLIENT, WEBSOCKET. We may also look over the names of the packages/groups for the build system and linux distros -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] topos module seems to break re-SUBSCRIBE routing to downstream destinations (#1724)
by George Diamantopoulos 18 Nov '20

18 Nov '20

### Description Kamailio seems to fail to properly route in-dialog SUBSCRIBE with the topos module enabled. In this configuration, SUBSCRIBEs are expected to be delivered to a downstream UAS, an asterisk instance in the internal network. record_route() is executed for all initial requests, including SUBSCRIBEs. Routing is performed correctly with the topos module disabled, no other modifications were needed.  ### Troubleshooting I haven't been able to work around this issue in any other way other than disabling the topos module. #### Reproduction The configuration used is a heavily modified version of the example configuration file, but the handling of SUBSCRIBEs is generally simple. The initial SUBSCRIBE is subject to some tests, the R-URI is edited and dispatched to a farm of asterisk servers based on some criteria. Record Routing is enforced, so subsequent in-dialog re-SUBSCRIBEs are expected to be routed with loose_route(), which doesn't seem to handle things properly.  #### Debugging Data I'm attaching kamailio logs with debug=4, cfg_trace  #### Log Messages See attachments  #### SIP Traffic Please see: https://www.cloudshark.org/captures/d2643aae7f2a  ### Possible Solutions Using topoh instead for topos, but unfortunately this will break communication for other reasons (messages too large/UDP fragmentation for some peers). ### Additional Information * **Kamailio Version** Tried with kamailio 5.1.6 and kamailio 5.3.0-dev0 deb.kamailio.org repositories were used to acquire binaries for both versions * **Operating System**: Debian Stretch  [resubscribe.log](https://github.com/kamailio/kamailio/files/2586440/resubsc… -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] uri_restore_rcv_alias() tried twice for local request (#2014)
by Alex Hermann 18 Nov '20

18 Nov '20

### Description While debugging an issue with locally generated in-dialog requests I stumbled upon some weirdness with the alias functionality from the nathelper module. The dialog modules tries to handle an alias parameter when sending an in-dialog request by calling ```uri_restore_rcv_alias()``` in the function ```build_dlg_t()```. A few instructions later, the same is attempted by the tm module in the function ```req_within()```. It seems to me that the attempt by the dialog module is redundant and can be removed. And while at it, IMHO it should be removed from the tm module too. This is functionality introduced by the nathelper module. Nowhere in the documentation it is mentioned there is some automatic handling of the alias parameter. If handling is needed for local requests, the script writer can call ```handle_uri_alias()``` from within local_route. If the functionality has to stay, may I suggest that the code in the nathelper module makes use of the ```uri_restore_rcv_alias()``` function instead of having its own duplicate implementation. Less maintenance, easier debugging. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] rtpengine: stats for rtpengine command and reply from rtpengine (#1699)
by Surendra Tiwari 18 Nov '20

18 Nov '20

### Description rightnow, there is no stats about command sent to rtpengine and getting reply from rtpengine. There should be a stats that will tell that number of offer request sent: number of answer request sent: number of delete request sent: number of failed request for offer [after retry]: number of failed request for answer [after retry]: number of failed request for delete [after retry]: This will help to identify actual number of failed request.  ### Troubleshooting #### Reproduction  #### Debugging Data  ``` (paste your debugging data here) ``` #### Log Messages  ``` (paste your log messages here) ``` #### SIP Traffic  ``` (paste your sip traffic here) ``` ### Possible Solutions  ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` (paste your output here) ``` * **Operating System**:  ``` (paste your output here) ``` -- You are receiving this because you are subscribed to this thread.
