One of my friend has about 70 members in his organization and many are not in the office network.They They are currently using their personal Yahoo messenger/Gtalk/MSN accounts for official chat. He wants a unified chat service so that only the officials employees are there in the chat.
In one of my company where I used to work, we used to chat via MSN messenger which worked only on the VPN and we could login using our official email ID's. I cannot remember how exactly this was achived, may be our office used a MSN chat server ,
But this is a different case. there is no VPN.
Can you guys please suggest any solution for this Free or Paid?
PS: He works in a NGO but can invest even if the software is paid and does the job.
