XMPP URI for file transfer

Hello all,

I have a xmpp uri to initiate a chat= xmpp:user1@server.com

The uri launches Spark and initiates a chat with user1.

Now I would like to take this a step further by allowing a file transfer initiation.

Is there a string that would do this?

A year or so ago I found command line strings to do certain things with spark but cannot find this anymore.

Thanks!

It would be ideal to have some documentation for Spark on this. I am looking for a way to initiate a phone call through a uri. I tried several but does not seem that I got any that Spark support (if any).
