Summary:                    detect fsk caller-id with DT-AS start signal
Description: 
hi:
   our country(Taiwan) use ETSI Standard ETS 300 659-1 to send caller-id.
the caller-id format may be DTMF or FSK. with the newest patch in issue
9096
(9096-1.6.2-branch.diff), the DTMF part is solved now. but asterisk still
can not detect the FSK part. 

   in the standard the FSK will send with a DT-AS (dual tone alerting
signal) start. the method is described in pdf below(page 12):
    http://www.araxinfo.com/~bacvic/ets_30065901.pdf

   I wonder if asterisk can treat this kind of FSK just like the DTMF in
issue 9096. issue 9096 add option "cidstart=dtmf" to chan_dahdi.conf. can
we add "cidstart=dtas" or "cidstart=fsk" to detect FSK also?
  
   I can help for testing if someone would like to give a patch. 
   thanks!!
