Hi Guys, Just new to Asterisk and am completely stumped. I have created two accounts as instructed. Please see below for the config of the user accounts. [Peter] type=friend host=IP address disallow=all allow=ulaw allow=alaw callerid=Peter <6004> secret=XXXXXXX context=default port=9060 nat=force_rport,comedia deny=0.0.0.0 permit=IP/255.255.0.0,IP/255.255.0.0,PrvIP/255.255.0.0, PrvIP/255.255.0.0 When attempting to register there appears to be something not allowing the authentication of the client against Asterisk. I am getting a 401 Unauthorized on first attempt and then 403 (Bad auth) on second. Is there any ACL config that I have missed which is not allow a good authentication. I have enabled nat and allowed all public and private IP's of the two clients with masks. The CLI console returns the following: ignore - Apr 16 11:09:57] NOTICE[24359]: chan_sip.c:27724 handle_request_register: Registration from '"6004"<sip:6004@xx.xx.xx.xx:9060>' failed for 'IP:57836' - No matching peer found [Apr 16 11:09:57] NOTICE[24359]: chan_sip.c:27724 handle_request_register: Registration from '"6004"<sip:6004@IP:9060>' failed for 'IP:57836' - No matching peer found serverIP*CLI> Have searched under No matching peer found and although there is some info on this it does not appear to satisfy my situation. Please help. Best Regards, Peter --- This email is free from viruses and malware because avast!
