Greetings,

I did some testing and onsend route is not executed on local generated requests.

I asked if they work the same way because for relayed requests, the on send is the last route before sending the packet.

I'm asking this because I'm trying to debug an issue with my probings via dispatcher, where some OPTIONS requests are not being sent to its destination. I got a log on local-request and all OPTIONS are logging there correctly. However, if i do a pcap capture on the kamailio machine, not all options are there. That being said, i want to make sure that the problem is not in my Kamailio configuration and it is sending the correct number of packets.

Best regards

Greetings,

Does "event_route[tm:local-request]" works like onsend route ?

no, event_route[tm:local-request] is for requests initiated by Kamailio via tm module (but other modules can be the source of the requests, as they use internally tm module, like msilo, uac, ...).

I'm having some problems and i'm using local-request to debug and i found this on the documentation : "Executed after the tm module has sent a local generated, transaction stateful request."

That was misleading indeed and wrong, because it is executed before sending out the request. The content of the request can still be changed there.

I'm logging all the requests that go through this route. Is this really the last place before kamailio send the request?

I am not sure if the onsend_route is executed for local generated requests -- it was desinged initially to be executed for requests that are received and forwarded by kamailio. So you may need both event_route[tm:local-request] and onsend_route to catch all outgoing requests. In other words, the onsend_route is the last one executed before sending out, where the content of what is going to be sent cannot be changed, but you can still drop the request. If you don't see there the local generated requests, then you have to use also event_route[tm:local-request].

If the request is logged here, is there anything more in kamailio that can stop the request (pipelimit, etc) ?

Stopping the request in event_route[tm:local-request] and onsend_route can be done by using 'drop'. When you do it, being it based on pipelimit, userblacklist, etc ..., it is up to you.

If a packet gets logged on this route does that mean that it was already sent?

No. Afaik, there is no event_route executed after the request was already sent. Although it might be useful for doing some ops that should not add delay to routing the request...

Cheers,
Daniel
