Presence Web Service API Support
The Presence Web Service is an open interface that allows client applications to share user presence information with IM and Presence Service. Third party developers use this interface to build client applications that can send and retrieve updates about the presence state of a user. Note the following restrictions about Presence Web Service API support:
-
For interdomain federation over SIP, you can use the Presence Web Service API to obtain rich presence information from non-Cisco clients, but basic presence for non-Cisco clients is not supported.
-
For interdomain federation over XMPP, you cannot use the Presence Web Service API to obtain presence information from non-Cisco clients.
For more information about the Presence Web Service, see the IM and Presence Service Developer Guide at https://developer.cisco.com/site/collaboration/call-control/unified-presence/documentation/index.gsp.
