Support for SIP NOTIFY XML-Service
The Cisco SPA300 Series and Cisco SPA500 Series IP Phones support the SIP
NOTIFY XML-Service event. On receipt of a SIP NOTIFY message with an XML-
Service event, the IP phone challenges the NOTIFY with a 401 response if the
message does not contain correct credentials. The client must be furnish the
correct credentials using MD5 digest with the SIP account password for the
corresponding line of the IP phone.
The body of the message may contain the XML event Message. For example:
<CiscoIPPhoneExecute>
<ExecuteItem Priority="0" URL="http://xmlserver.com/event.xml"/>
</CiscoIPPhoneExecute>
Authentication:
challenge = MD5( MD5(A1) ":" nonce ":" nc-value ":" cnonce ":" qop-value
":" MD5(A2) )
where A1 = username ":" realm ":" passwd
and A2 = Method ":" digest-uri
