Description:Hi! I am in Taiwan. After looking for the specs of CallerID in Taiwan, I found that the CallerID detection from FXO failed because of DTMF, FSK/ETSI information sent before the first ring. The signalling of the start of callerid isn't polarity reversal. I am using the TDM400 with 3 FXO. Is it possible to add the CallerId detection before first ring in future release ?
