Hello,

The PUA module is usually used with some of the other pua_* modules, e.g. pua_rpc for using RPC commands, pua_usrloc for using usrloc information and so on.

Have a look to the pua readme first section, it lists all the modules.

Regarding the general flow, usually you do handle_subscribe(..) from the presence module in the request_route for a certain event type. If a client is subscribed with the correct event type to an entity, you can use eg. pua_rpc to generate a NOTIFY for this event type and entity.

Cheers,

Henning

Subject: [SR-Users] Question about UAC and PUA modules routing behavior

Hello, I have some trouble to figure out how routing works when the request coming from the kamailio itself (used as a user agent per example) .I try to use presence PUA... modules. The issue I have is the NOTIFY requests aren't sent to the good destination; it doesn't seems to obey to the contact or other informations when the device did a SUBSCRIBE.

I don't want to ask to troubleshoot the presence module directly

I just want to know how Kamailio deals with request coming from Kamailio itself (in the case of a NOTIFY generated by PUA_... modules


My mains questions are:

Does the pua modules when generating request  like NOTIFY will pass through request_route ?

Does the pua modules when generating  request  like NOTIFY will be sent only when t_relay() is used or UA kamailio based request bypass all the logic of the Kamailio proxy behavior ? 

I'm trying to understand if I can modify the NOTIFY request to change destination before the "routing decision" is made by Kamailio


Kamailio 5.6.0 used as :
-proxy to remote pbx for call dialog
-registrar/location server
-media relaying and nat management
-...and I try to use it as a presence server instead to use the pbx behind kamailio
