Thank you Daniel, everything is cleared now.

Hello,

during the early state of a dialog (like trying, ringing, ...), there can be many outgoing branches of the initial INVITE (think about a call going to a user which has two sip phones registered for same account). It's the reason dialog waits to see which branch is responding from callee side.

Also, it's not mandatory that all 1xx responses have a Contact header.

Anyhow, you can implement your own logic of storing dialog attributes in a custom database table using sqlops module, doing insert/update/delete at various events: initial invite, receiving a 1xx response as well as for 2xx and 3xx+, cancel, bye ...

Cheers,
Daniel

Greetings list,
I am using dialog aur dispatcher modules for calls distribution across multiple gateways. I am able to get number of active dialogs against a gateway but could not get early dialogs going on particular gateway.

Dialog information is inserted in database only for state 4. Also, I tried to use dlg_list command to get early dialogs. I see call statistics but "callee_contact::" is empty untill call is answered.

for ringing I am getting this.

root@debian:/usr/local/kamailio/sbin# ./kamctl fifo dlg_list
dialog::  hash=3443:9422
        state:: 2
        ref_count:: 1
        timestart:: 0
        timeout:: 0
        callid:: GGjl58SQ32LXQB1dV2-CBA..
        from_uri:: sip:1015@192.168.10.39:5060;transport=UDP
        from_tag:: 652ee907
        caller_contact:: sip:1015@192.168.10.41:55842;transport=UDP
        caller_cseq:: 1
        caller_route_set::
        caller_bind_addr:: udp:192.168.10.39:5060
        callee_bind_addr::
        to_uri:: sip:1010@192.168.10.39:5060;transport=UDP
        to_tag::
        callee_contact::
        callee_cseq::
        callee_route_set::

callee_contact:: is empty.

Is there any way to get early dialog info againts a gateway.? Or any way to insert early dialog into database with callee_contact not empty?

Best Regards,
Aqs Younas
