Well, I did a test call to you (if that was your number in the noisy feedback message). I got
SIP/2.0 480 Temporarily Unavailable and also
SIP/2.0 477 Unfortunately error on sending to next hop occurred (477/SL).
I also saw this message
Code:
Warning: 392 64.34.173.199:5060 "Noisy feedback tells: pid=11520 req_src_ip=72.51.47.59 req_src_port=5060 in_uri=sip:*010317410@64.34.173.199:5060 out_uri=sip:317410@192.168.1.105:4221;transport=tcp;line=qi34n984 via_cnt==2"
Is the address 192.168.1.105 something on your LAN?
