It already is an option on the conference configs: timer-name.
This could be use for sip as well for the same reasons.

I've suggested this to be done a few times already.  Ideally sangoma should
make something similar.
For scale-ability I also recommend looking at mod_timerfd and doing it in a
similar fashion to use one single dadhi channel to service N threads.
