Hello,
regarding your questions:
1. Besides from the Kamailio core, you only need to use the modules that are actually
necessary for your configuration. There are over 220 modules, so they are of course not
always used.
2. Can't comment with too much detail here, but generally speaking, Kamailio provides
xcap modules and can also support external xcap servers I think. Regarding the logic,
certain things can be configured in the configuration, some things are module parameter or
depends on the processed presence events. You can supply presence updates with SIP
messages, over the RPC interface, over json strings to name some options.
3. Kamailio for presence is usually chosen in particular because of other solutions are
not able to fulfil performance requirements. The concrete performance numbers depend of
course on your configuration, your database, your storage etc.. You probably need to make
some tests here.
Cheers,
Henning

Subject: [SR-Users] Kamailio as a Presence server only
I all, I'm looking into Kamailio as a solution to replace our current Presence
Server in our IMS Network, but feeling a bit overwhelmed by the feature size
and complexity of Kamailio. I have a few questions (some might be dumb), if
you guys could help me I would appreciate.
1. As I only need Kamailio as a Presence Server (with XCAP and SIP Interface),
is there a way to install only the necessary components and/or modules? Our
security team would probably raise some questions if we need to install
unused code on the network. For what I could investigate, the modules i
would need are:
* Presence
* Presence_XML
* Xcap_server
* xhttp
* RLS
* Pua
* database
* sl
* tm
Am I missing something?
2- As refered on point 1, our server will need a xcap and sip interface. Some
presence updates will come through XCAP, others from SIP Publish. My
question is, whenever a presence update is made through XCAP interface, will
the kamailio server trigger the necessary SIP Notify to notify all Subscribed
users ? I ask this because this was a problem with our current supplier.
3 - our client is a bit "peeky" with performance. I found here
(https://www.kamailio.org/wikidocs/kemi/performance-tests/5.2.x/#results)
some performance tests, but for what i can see the test primary goal was to
test the response time. Is there any resource on "requests per second"?
Thanks in advance for all the help
David Salvador
