If 202 didn't answer,even it rings for a long time. CDR Report List will have a record like below. Source Dest. Status Duration 201 202 NO ANSWER 0 But, When I use SIP phone to call my mobile number via Zap trunk. Even I didn't answer that call. The CDR Report List will have a record like below. Source Dest. Status Duration 201 0913111111 ANSWERED 12 But that 12 seccond is the time that I ring the phone. Can someone give me a hint how to fix this?
