For the Kamailio presence server to understand the "dialog" event
package you need to use presence_dialoginfo module. (this is necessary
to handle the SUBSCRIBE requests).

The second thing is: where is the dialing information coming from? Some
phone will send PUBLISH requests with the dialog state on dialog
changes. Then it should already work.

If your phones do not PUBLISH the dialog state to the proxy, then there
is a workaround possible in Kamailio. If Kamailio uses the dialog
module, then the dialog changes (calls) can be derived from dialog state
and published to the presence server (either an external presence server
or the same Kamailio proxy instance) by using the pua_dialoginfo module.
