If you don't use dialog for something else than tracking cseq updates, then maybe it works by not using dlg_manage() for this calls. Otherwise, digging in the code would be the way to go.

Thanks for the reply Daniel,

I did see references to it in the source but was hoping that there was some way to implement this in config.
If you do find a workaround please let me know, otherwise I'll just create the patch and upstream it to the next development release.

Hello,

the callbacks are in the code, executed just after receiving and before sending to the network, I don't think there is no possibility to interact with the callbacks from the config file.

Having the possibility to turn on/off the cseq update likely requires some C coding, I don't remember by heart any way to do it right now, but I haven't had the time to check the code and refresh how is done to see if any workaround can be used at this moment.

Cheers.

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?
