CUCM API to develop a Gadget

[venchalam78]

Hi 
I am looking for API where i can use ti develop a gadget to provide call control features such as Make call / hold / Retrieve / transfer / Conference.  This is not via agent login. Non-ACD calls for non voice agent.

Please do share the me the details if any of the API available for the same.

For 3rd party call-control functionality, you will be looking at the TAPI (C/C++) or JTAPI (Java) APIs:

Not sure what kind of widget technology you are targeting, but if browser-baser then Jabber may be a possibility:

For TAPI/JTAPI you are likely looking at a 3-tier architecture, where there is a central TAPI/JTAPI CTI application offering some kind of RPC API for clients (i.e. widget) - this is probably what I would recommend, as it is efficient/stable/well-supported.
Jabber Web Voice/Video SDK is installed/works at the individual browser client level, but uses a fairly clunky extension+native-add-on mechanism.
