SER sends a 200 ok WITH a digest authentication request. The client should then send another REGISTER message with the key that it recieved in the 200 ok. SER should then get the 2nd message and send another 200 ok verifying that the client did use digect authentication. George Hi all, I've this problem when I start my soft phone client with ser: Warning: 392 192.168.87.252:5060 "Noisy feedback tells: pid=424 req_src_ip=192.168.87.71 req_src_port=6756 in_uri=sip:ser.mydomain.pri out_uri=sip:ser.mydomain.pri via_cnt==1" I look that when my client try to register to ser, it received an 200 ok response, but my client resend a register request again and again, this loop cause a latence in my traffic. Any idea? In attach is my config file Tnx -- +----------------------------------------------------------------------+ | Ing.
