How to make TDM2400 pick up the line instantly

Hello.
I have TDM2400 with FXO ports. It takes about 3 seconds for Asterisk before it starts executing dialplan on incoming call. If sees the ring almost instantly:

[Jun 7 21:58:30] NOTICE[5925]: chan_zap.c:6364 ss_thread: Got event 18 (Ring Begin)…
[Jun 7 21:58:30] NOTICE[5925]: chan_zap.c:6364 ss_thread: Got event 2 (Ring/Answered)…

but then it takes 1-2 rings before dislplan execution begins.

Is there an option specifying how long to wait before picking up the line?

Thanks

Answering to myself :smile:

cidstart=polarity
in the zapata.conf does the trick
