I have to use a specific softphone, HelpCaster, but it can not pass the authentication stage. However it can authenticate with OpenSips server! What I had noticed is that it uses static realm with OpenSips therefore I'm trying to do the same. recv 292 bytes from udp/[209.82.10.250]:3458 at 16:35:24.758862:    ------------------------------------------------------------------------    REGISTER sip:209.82.10.235 SIP/2.0    Via: SIP/2.0/UDP 209.82.10.250:1059    From: sip:1001@209.82.10.235    To: sip:1001@209.82.10.235    Contact: sip:1001@209.82.10.250:1059    Call-ID: fc383368-e3e0-4c32-b87b-c3127d0cc2d8@192.168.10.23    CSeq: 597775306 REGISTER    Content-Length: 0    Expires: 3600      ------------------------------------------------------------------------ send 582 bytes to udp/[209.82.10.250]:1059 at 16:35:24.763948:    ------------------------------------------------------------------------    SIP/2.0 401 Unauthorized    Via: SIP/2.0/UDP 209.82.10.250:1059    From: sip:1001@209.82.10.235    To: <sip:1001@209.82.10.235>;tag=7yam2F01ZH3vH    Call-ID: fc383368-e3e0-4c32-b87b-c3127d0cc2d8@192.168.10.23    CSeq: 597775306 REGISTER    User-Agent: FreeSWITCH-mod_sofia/1.0.2-hacked    Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, PRACK, MESSAGE, SUBSCRIBE, NOTIFY, REFER, UPDATE, REGISTER, INFO, PUBLISH    Supported: timer, precondition, path, replaces    WWW-Authenticate: Digest realm="209.82.10.235", nonce="40b63193-85c2-4ed9-874e-c03f81be313d", algorithm=MD5, qop="auth"    Content-Length: 0      ------------------------------------------------------------------------ recv 466 bytes from udp/[209.82.10.250]:3458 at 16:35:24.772834:    ------------------------------------------------------------------------    REGISTER sip:209.82.10.235 SIP/2.0    Via: SIP/2.0/UDP 209.82.10.250:1059    From: sip:1001@209.82.10.235    To: sip:1001@209.82.10.235    Contact: sip:1001@209.82.10.250:1059    Call-ID: fc383368-e3e0-4c32-b87b-c3127d0cc2d8@192.168.10.23    CSeq: 597775307 REGISTER    Content-Length: 0    Expires: 3600    Authorization: Digest username="1001",realm="209.82.10.235",nonce="40b63193-85c2-4ed9-874e-c03f81be313d",response="eebe0ea43319e82cc5f6dba5877de706",uri="sip:209.82.10.235"      ------------------------------------------------------------------------ send 458 bytes to udp/[209.82.10.250]:1059 at 16:35:24.774354:    ------------------------------------------------------------------------    SIP/2.0 403 Forbidden    Via: SIP/2.0/UDP 209.82.10.250:1059    From: sip:1001@209.82.10.235    To: <sip:1001@209.82.10.235>;tag=873c4aH5vtSFD    Call-ID: fc383368-e3e0-4c32-b87b-c3127d0cc2d8@192.168.10.23    CSeq: 597775307 REGISTER    User-Agent: FreeSWITCH-mod_sofia/1.0.2-hacked    Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, PRACK, MESSAGE, SUBSCRIBE, NOTIFY, REFER, UPDATE, REGISTER, INFO, PUBLISH    Supported: timer, precondition, path, replaces    Content-Length: 0      ------------------------------------------------------------------------ Thanks!   Message: 2 Date: Tue, 17 Feb 2009 11:39:58 -0600 From: Brian West <brian@freeswitch.org> Subject: Re: [Freeswitch-users] Realm Value To: freeswitch-users@lists.freeswitch.org Message-ID: <2ADB8FA0-3E87-4C99-9A6F-F09C6E0F5DB8@freeswitch.org> Content-Type: text/plain; charset="us-ascii" I'm trying to get a clear picture of what you're trying to accomplish. Why would you need/want to set a static realm? Anyway can you collect sip traces? /b On Feb 17, 2009, at 8:51 AM, Ali Al-Rubaie wrote:
