Thanks for your reply......Yes i am using D300JCT..and protocol is ISDN . i am using ISDN PRI.
i read that gc_AcceptCall termimate event GCEV_ACCEPT after ring back parameter. but in my application it returning immediately.
My actual requirement is i want to give 2 time ring back on incomming call....then disconnect the call without answering....so i am calling disconnect on GCEV_ACCEPT event..but when incomming call come gc_Accept API giving GCEV_ACCEPT and call is disconnecting without any ring to caller.
