Hello,

$dlg_var(cseq_diff) is incremented after sending the invite out from failure route, being done when forwarding callback in dialog detects that the cseq value has to be incremented.

I am going to test and see if there is an issue -- uac_auth() should set some internal flag to tell dialog to increment cseq.

Cheers,
Daniel

Hello. I need to increment CSeq value for INVITE with Auth params when use UAC_AUTH for outgoing calls to provider.

Kamailio 4.2 may increment this using dialog module 

http://by-miconda.blogspot.de/2014/10/kamailio-42-tips-7-increment-cseq-for.html

Now I experements with this and var $dlg_var(cseq_diff) and at transaction way int have NULL value. I can not understand why

My config is:

 # ----- dialog params

modparam("dialog", "db_url",DBURL)

modparam("dialog", "db_mode", 1)

modparam("dialog","table_name","dialog")

modparam("dialog", "dlg_flag", 4)

modparam("dialog", "initial_cbs_inscript", 1)

modparam("dialog", "profiles_with_value", "caller")

modparam("dialog", "default_timeout", 60)

modparam("dialog", "track_cseq_updates", 1)


route config is 

at request route

if(is_method("INVITE") && !has_totag()){

$dlg_ctx(timeout_route) = "DIALOG_END";

$dlg_ctx(timeout_bye) = 1;

dlg_manage();

xlog("L_INFO","Dialog manage is {$ct}\n");

} } t_relay();

next I handle failure reply because 407 reply is recieved failure_route[MANAGE_FAILURE] { route(NATMANAGE); if (t_check_status("401|407")){ xlog("L_INFO", "Reply from provider on failure: $tU"); xlog("L_ERR","401/407 - Unauthorized. ($ci .) ($rm) from ($fu) (IP:$si:$sp) to ($Ri:$Rp). Must be authorized with digest Auth."); avp_print(); xlog("L_INFO", "CSeq diff: $dlg_var(cseq_diff)"); uac_auth(); xlog("L_INFO", "UAC_AUTH(): $tU"); append_branch(); t_relay(); } if (t_is_canceled()) { exit; } } As you may see i logging $dlg_var(cseq_diff) value and now it NULL. So I can not understand why? What wrong I do? Thanks for advice.
