I have 2 remote locations each running their own openfire server. The 2 servers are connected by a private vpn, so users on both sides can chat with each other. All the users dont have an internet connection. Just connections to their local openfire servers.
I wanted to know what are the best options for voice calling or voice chatting between the users locally and over the vpn?
If there are 3rd party options that can integrate with the openfire users that is ok also. We are currently using Spark as our chat client.
why dont you guys use Conversations(android app) or install the jsxc web browser plugin for Openfire (can also do video calls) there is also the Pade plugin for Openfire(this one is the best choice for company video calls and conferencing etc.)
