I have an Asterisk(1.2.5) service with a TDM400 and 3 FXO modules installed. Everything works just fine, except the callerid from PSTN. After asking the local telecom, I found that the CallerID is sent before the first ring. The current CIDSIGNALLING supportted are DTMF and FSK/ETSI. Are there any ways to fixing up this mismatch ? If you have any information , plz let me know. Thanks for your kindly help !!!
