System speed has VERY little to do with this.  If Asterisk expects to
get Caller*ID and the PSTN line does not have Caller*ID service on the
line. Asterisk has to wait until the beginning of the second ring before
giving up on getting any Caller*ID.  If your PSTN line doesn't have
Caller*ID service then tell Asterisk not to expect Caller*ID then the
delay will be MUCH less.  This is covered over and over and over again
in the mailing list archives.
