When you add a new contact to your Jabber roster, the client awaits a confirmation from that contact that allows you to subscribe to their information. I have never had this work perfectly with all instant messaging clients. Sometimes an exit and relaunch of the client side applicaitons for both parties will resolve this issue, but that should not be necessary. A quicker fix is to use CommuniGate Pro WebMail to set your 'Sees Us' and 'Seen by Us' instant messaging (IM) settings for all IM clients you test or use, SIP and XMPP.

Login to WebMail and select the 'Basic' skin interface.



After logging In, the upper right area of the interface should show a Buddies link.



Account users can send buddy/contact subscription requests with the 'Request' button on this page.



Requests that were previously sent to you by other contacts will also appear here and you can approve or deny their subscription to your information.



I often use this interface to correct or clean the Group names I use for contacts. This utility allows me to unify how I organize my IM contacts information. Having this on the server side is very useful for management of this data especially when you use more than one instant messaging client.
