Support for SIP NOTIFY XML-Service
The Cisco SPA 500 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
