Hi Everybody, Is there any plug-in available for SIP Communicator to save contact list in the server side. I mean when the SIP Communicator register itself to server the server will save to contact list to its own persistence storage. So the client doesn't need a local copy of contact list. I am using OpenIMSCore and OpenSER. I am just wondering whether this functionality is already available in SIP Communicator or not? If not then how much work has to be done to implement in properly? I am just looking for some idea about this. So that I can make an estimation about this implementation. I am looking forward to hearing from all of you. Best regards Yeasin Habib
