Say for eg: REGISTER sip:192.168.104.113 SIP/2.0 Via: SIP/2.0/UDP 192.168.104.110:5060;branch=z9hG4bKbab835b91939ee5dd Max-Forwards: 0 From: <sip:192.168.104.113:5060>;tag=4be5501b2b To: <sip:[email protected]:5060> Call-ID: 0f2633d154e734df CSeq: 2 REGISTER Allow: INVITE, ACK, CANCEL, BYE, NOTIFY, REFER, OPTIONS, UPDATE,PRACK, SUBSCRIBE, INFO Contact: <sip:[email protected]:5060;transport=udp>; expires=3600 User-Agent: SipTool Authorization: Digest username="001AA040A", realm="abcd.com", cnonce="8684c3c0", nc=00000001, qop=auth, uri=SIP:192.168.104.113, nonce="4805c00a969ec901f146d1927b99fe102ffbc8e21b64fe55", response="ad9d72e63ff808fe020a07813962023f", algorithm=MD5, opaque="" Content-Length: 0 Observe the "uri" field value in the above Register request. RFC 3261 in Section 22.4 specifies the following: 2. The BNF in RFC 2617 has an error in that the 'uri' parameter of the Authorization header field for HTTP Digest authentication is not enclosed in quotation marks. (The example in Section 3.5 of RFC 2617 is correct.) For SIP, the 'uri' MUST be enclosed in quotation marks.
