How can I set up 2 Jabber clients, so I can make 2 way call between them? Based on what I am reading, I cannot open 2 different VPN connections with the same credentials, and I cannot run 2 instances of the Jabber for different users on a single desktop that has VPN connection to the sandbox. Does making calls between two users on a sandbox require JTAPI application, or can be done in more simple way?
