Using jabber protocol handler to open a chat conversation to a user in a federated domain

[LondoMollari82204]

We have some web applications in which we use XMPP protocol handler to open a chat conversation with a user.

For example, the following URL xmpp:johndoe@mydomain.com will launch my jabber and open a chat conversation John Doe.

This works fine.

But, we also have XMPP federation with another organization (otherdomain.com)

When we try to use the same protocol handler to open a chat with a user at the federated domain - for example:

xmpp:janedoe@otherdomain.com

clicking this URL launches jabber, but jabber does not open a new chat with janedoe@otherdomain.com. No new chat is opened; and if there already is a chat conversation open with Jane Doe, then this chat conversation is not selected.

The above behavior is the same if we use other protocol handlers such as IM: or CISCOIM:

Any pointers as to why this might be? is there some way we could solve this or work around this?
