Hello, I would like to try customizing the fr_timer for the OPTIONS keep-alive msgs transactions that the dialog module sends. I tried to call t_set_fr() function from inside the dialog modules's code (in dlg_req_within.c , in dlg_send_ka() function after the call to d_tmb.t_request_within(&uac_r);

But it seems that this tm function is not available from inside other module's code.

Is the above is the correct place to try and do it, and how can I programmatically ,inside a module's code, adjust fr_timer?

On a side note, i followed the call flow from dlg_send_ka() down to the t_uac_prepare() function of tm module, where the fr_timer is set. In there, there is this comment+code:

/* init timers hack, new_cell->fr_timer and new_cell->fr_inv_timer

  * must be set, or else the fr will happen immediately

  * we can't call init_new_t() because we don't have a sip msg

  * => we'll ignore t_set_fr() or avp timer value and will use directly the

  * module params fr_inv_timer and fr_timer -- andrei */

 new_cell->fr_timeout=cfg_get(tm, tm_cfg, fr_timeout);
 new_cell->fr_inv_timeout=cfg_get(tm, tm_cfg, fr_inv_timeout);
 new_cell->end_of_life=get_ticks_raw()+lifetime;

Does this mean that it cant be done in a straighforward way?

Any advice on how I can achieve the customized fr_timers for those messages?

Thanks.
