Calling all SIP gurus-- I'm trying to register my asterisk to an ISP's SIP gateway. I'm getting authentification errors. Here's the results of SIP DEBUG against it's IP. [I've tweaked all confidential fields so as to protect the innocent (namely, me).] --- (9 headers 0 lines)--- Responding to challenge, registration to domain/host name myfavoriteisp 12 headers, 0 lines Reliably Transmitting (no NAT) to 66.62.88.226:5060: REGISTER sip:voip.myfavoriteisp.net SIP/2.0 Via: SIP/2.0/UDP 192.168.134.247:5060;branch=z9hG4bK32fe0b71 From: <sip:3073334444@voip.myfavoriteisp.net>;tag=as133ed01a To: <sip:3073334444@voip.myfavoriteisp.net> Call-ID: 145577bf359d45924b54880e68ea5541@192.168.134.247 CSeq: 146 REGISTER User-Agent: Asterisk PBX uthorization: Digest username="3073334444", realm="voip.myfavoriteisp.net", algorithm=MD5, uri="sip:voip.myfavoriteisp.net", nonce="27a4f823b14f298bbbbbbbbbbbbbbbb", response="6ccccccccccccccccccccccccccccccc", opaque="", qop="auth", cnonce="abcdefab", nc=00000001 Expires: 120 Contact: <sip:s@192.168.134.247> Event: registration Content-Length: 0 --- phone*CLI> <-- SIP read from 45.123.29.97:5060: SIP/2.0 401 Unauthorized Via: SIP/2.0/UDP 192.168.134.247:5060;received=216.98.159.235;branch=z9hG4bK32fe0b71;rport=5060 From: <sip:3073334444@voip.myfavoriteisp.net>;tag=as133ed01a To: <sip:3073334444@voip.myfavoriteisp.net>;tag=SD4g5g799-192.168.100.21 +1+0+ca2d1757 Call-ID: 145577bf359d45924b54880e68ea5541@192.168.134.247 CSeq: 146 REGISTER WWW-Authenticate: Digest realm="voip.myfavoriteisp.net",nonce="f6f7a243b39ace410a72f38aa6ca1a30",stale=false,algorithm=MD5,qop="auth" Server: DC-SIP/2.0 Content-Length: 0 --- (9 headers 0 lines)--- May 23 09:56:39 NOTICE[9021]: chan_sip.c:8290 handle_response: Failed to authenticate on REGISTER to '<sip:3073334444@voip.myfavoriteisp.net>;tag=as133ed01a' Destroying call '145577bf359d45924b54880e68ea5541@192.168.134.247' The above gets repeated over and over. I restart asterisk after I comment out the register line to stop the cycling. Am I doing anything obviously wrong?
