Hi , I used open internet, i really doubt if there is any NAT issue here.
But my config file(kamailio.cfg) shows : tcp-connection-lifetime=3605 But i dont know what is the registration expire time . How can i see the registration expire time? also my lin phone sends keep alive right? can you please help me how can i see connection close parameter during forward/reply? i dont know where to set them? Please suggest me the correct link to find tcp paremeter and cook book.
