HI List,
I have two SIP phones. one is 6002, w: which is behind a NAT, and another is 5009 which has public IP . When a call between 6002 to 5009, the 6002 cannot hear any from 5009, and 5009 did hear from 6002. And in the sip debug, I see following message Sip read: SIP/2.0 481 CallLeg/Transaction Does Not Exist and I specified in sip.conf [6002] type=friend host=dynamic nat=1 qualify=yes [5009] type=friend host=dynamic nat=1 qualify=yes Can anyone help me what can be wrong ???
