Hi Olle,
Thank you for your answer. Having a look at the dialog module documentation
I think I can make use of parameters ka_timer + ka_interval together with
dlg_set_property() function.
Do you know if I can manipulate the generated OPTIONS in any way? (like
append_hf() ) Not able to test this at the moment but I assume it should
work.
Cheers,
Stefan

Hello,
What is the simplest way to configure Kamailio to generate periodical
OPTIONS to the caller, for an established dialog?
Can you give me some starting references?
To be SIP correct, a proxy may not insert any transactions in a dialog
between two endpoints. The endpoints have the cseq counter and inserting
anything will mess with the CSEQ.
Having said that, the dialog module has a keep-alive function that does
this. It may generate strange error messages which is fine. You want to
test the behaviour on a per-device basis.
Cheers,
