Now, my server have asterisk, openfire+asterisk-im and sip phone plugin, x lite and spark. In my sip.conf have extension 100, 200, 300 and 400. I define Ext. 100 = userA, Ext. 200 = userB, Ext. 300 = userC and Ext. 400 = userD.
This detail of phone mapping.
On labtop A, installed x lite and spark and x lite=Ext.100, spark=userC.
On labtop B, installed x lite and spark and x lite=Ext.200, spark=userD.
Now, on x lite Ext.100 can call to Ext.200. On spark userC can chat userD. The x lite it have IM(chat) feature but i don't use it. I want to use x lite chat(IM) with spark. How to do it?.
