Hi Sunil!

Kamailio 1.4 does not support the "dialog" event package. You have to use Kamailio "trunk" version. Trunk includes 2 new modules:

PUA_DIALOGINFO: generates PUBLISH requests to publish the dialog state PRESENCE_DIALOGINFO: processes PUBLISH requests, aggregate dialog information and send it with NOTIFY to the watcher

Please see the detailed READMEs of these modules. http://www.kamailio.org/docs/modules/devel/

Hi,

        I want to know that Kamailio-1.4.0-notls supports Dialog 

Event Package, If yes what configuration I have to do. If no the which version of the kamailio/OpenSER/OpenSIPS I have to use for the Dialog Event package support. Please go through the below call flow I have a problem.

I am using kamailio-1.4.0-notls and trying to use dialog event package. The above call flow is as follows.

1.   B an x-lite phone is Registered(B@kamailio) then C another 
   

x-lite phone is registered(c@kamailio)

2.   Now from my application I am registering A and got 
   

registered(A@kamailio).

3.   Now A is subscribing to B for the dialog event, so I am sending 
   

SUBSCRIBE message to kamailio server, that is I am sending SUBSCRIBE message from A@application to B@kamailio with the Event header.

4.   Now I got 202 for the SUBSCRIBE.
   
   

5.   Server Kamailio sends NOTIFY and then my application A sends 
   

200 OK.

6.   Now I will establish call between two x-lite phones B and C.
   
   
   
   
   
   

*Now My Question?*

When I establish call between B and C, I(Application A) have to get NOTIFY from kamailio server about the dialog event, I am not getting the NOTIFY for the dialog event since I have Subscribed to B for the Dialog event Package.

Finally I(A application) want to know that dialog changes in the B

Any help is appreciated to solve my problem. Advance thanks for the help.

**Thank You**

**Regards,**
