Dear Amit, The Sip Server must have implementation of RFC 4825 for SIP SIMPLE. You can implement the OpenXCAP for this from AG-Projects. OpenXCAP is an Open Source, easy extensible, fully featured XCAP server with TLS security and support for multiple realms. XCAP protocol allows a client to read, write, and modify application configuration data stored in XML format on a server. An XCAP server is used by the XCAP clients to store data like Presence policy in combination with a SIP server that supports PUBLISH/SUBSCRIBE/NOTIFY methods to provide a complete SIP SIMPLE server solution. The Project is hosted at *http://openxcap.org* <http://openxcap.org/> .
