I'm not 100% positive on what or how red sky is integrated. I know they support PIDF-LO for location data, but CER doesn't send that, the UCM tags it as it routes the call. I don't believe ALI information from the default ERL should make its way there live, but would have maybe been synchronized if you use V911, but I could be wrong.
I would ask RedSky if there's a special address or similar that can go into the configuration that would let them know that the call needs to go to their center for handling. Those calls are expensive I hear, so for a Jabber client perhaps the vendor's accompanying software is the way to go if it works with V911.
