[Asterisk-Users] Avoiding 2 ring callerid delay for calls that don't go to voicemail

[Steve Prior]

I have my dialplan configured for an incoming call on the FXO to connect right
through to a FXS on the TDM100P.  Because of the callerid the calling party
gets 2 rings before asterisk picks up and then it's another 2 before the caller
id shows up on the analog phone connected to the FXS module.  I understand that
the 2 rings are needed to collect CID, but is there any way to tell asterisk
that since it's passing right through to the phone to streamline the process
to 2 rings total instead of 4?  People will almost be at the point of hanging up
when I've just seen the CID at the phone for the first time.  The only time the
callerid would be used by Asterisk itself would be if the call goes to voicemail.

Any hints?
