[SR-Users] Dynamic CSEQ Updates

[Tyler Moore]

Hey kamailio team,

When are the callbacks in the dialog module for updating
$dlg_var(cseq_diff) called?
I am trying to dynamically enable / disable cseq updates (some specific
carriers need it and some don't) by setting $dlg_var(cseq_diff)=$null prior
to sending the request but it seems like the callback happens after
relaying.
For example I tried various locations:
- prior to t_relay()
- in onreply_route[]
- in failure_route[]
- in event_route[tm:local-request]
- in event_route[tm:local-response]

I also tried setting modparam("dialog", "initial_cbs_inscript", 1) and
calling dlg_manage() prior to routing and those didn't seem to be the right
callbacks either.

Either the callback that updates $dlg_var(cseq_diff) occurs after t_relay()
/ forward() is called or setting $dlg_var(cseq_diff)=$null has no effect.

Is dynamically turning CSEQ updates on / off possible by
overwriting $dlg_var(cseq_diff)?
Or would this require new logic in the dialog module to be supported?
