Hi; I'm using the received parameter to send a MESSAGE to unregsiter the first user that is registered to register the second one. Using: *modparam("usrloc", "received_column"* *modparam("registrar|nathelper", "received_avp",* and when I do a: select received from location; as you can see is null. +----------+ | received | +----------+ | NULL | +----------+ In IPV4 is working fine, but in IPV6 is not. Can you tell me how can I get this value? Im going crazy with that. … [View More]

Can't work around double SDP rewrite issue with rtpengine and config script SDP manipulation
by George Diamantopoulos 03 Jun '20

03 Jun '20

Hello all, I'm facing one of those cases where I need to edit the body of a SIP message, which is then to be fed to rtpengine for processing. Although I've taken every precaution I've read about on this list and elsewhere, I can't prevent the edited line from appearing twice in the outgoing message. The configuration file used is huge, so I'm going to try to provide a high-level overview here. But first, the things (I think) I know to be requirements, and which I have striven to meet: - … [View More]If SDP is to be edited, then all such processing is to be carried out in such a way in the script, so that msg_apply_changes() is run as many times as needed before rtpengine offer/answer/manage is called. - rtpengine offer/answer/manage is to be called only once per script iteration - msg_apply_changes can only be called in a request route, or in the core reply_route (i.e. *not* in tm-managed on_reply_route[XXX] blocks) In my case, additionally the following are true: - SDP processing (other than the one performed by rtpengine) takes place in one common route for all cases where it needs to happen. These are two at the moment in my scenario: - Early in the WITHINDLG route (of the example config file) - After the sanity checks in the reply_route (of the example config file) - msg_apply changes() is called once, for each script iteration: - right before rtpengine_manage() is called, provided that t_is_request_route() returns true (so that I don't accidentally call it from a branch route or anything) - rtpengine_manage() is called in its own route, which is very similar to the example config file's "NATMANAGE" route. Since NATMANAGE is called in all branch and on_reply_routes, I employ t_is_request_route() here to make sure it won't execute in those cases. - at the end of the "core" reply_route Now regarding the actual config-file-controlled SDP manipulation, it only consists of a single call to replace_body_str(). The purpose is to edit a line in the message body from something like: - a=fmtp:101 0-16 to something along the lines of: - a=fmtp:101 0-15 For replies, this works as expected. For in-dialog requests, however, I end up with both the original and the edited lines: a=fmtp:101 0-16 (the original line) ... other SDP stuff ... a=fmtp:101 0-15 (the edited line) If anyone could point out any misconceptions I have about msg_apply_changes, SDP rewriting from the script and rtp_engine_X() interoperability, I would be more than grateful. Thank you in advance and I apologize for the long read. Best regards, George Diamantopoulos [View Less]

Meaning of shmem stats and question on dmq dialog sharing behaviour
by George Diamantopoulos 02 Jun '20

02 Jun '20

Hello all, I've recently been experimenting with dmq, and I've noticed something that seemed a little odd. shmem use would often be abnormally high on otherwise idle kamailio nodes (literally, only dispatcher module OPTIONS were exchanged at the time besides KDMQ messages). After disabling the "enable_dmq" parameter for the dialog module, this sort of absurd behaviour ceased. To get a quantified idea of this change's effect, check out the following screenshot from our monitoring system: https:… [View More]
