by CEZEO software Ltd.   

LanTalk.NET office instant LAN messenger that work in LAN, WAN or Internet, without any server or internet access! Designed for business networks. In fact, in most companies LanTalk.NET replaced corporate e-mail for exchanging files and messages. For an additional fee you will get a custom version of LanTalk.NET.

No setup, no administrator, no server. The program does everything on its own. It does not require a server. Instead, the program uses TCP/IP and UDC protocols, and port 2307 (by default), to make sure that there aren't any problems with a firewall. All PCs "communicate" to each other directly. The application automatically determines which users are available on its own. Thus, there is no need to set up or administer the program.

Second, the program works with any network - Intranet, Internet, LAN, WAN, and VPN. It really makes a lot of sense. Instant messaging communication inside one office is great, but what if you need to discuss something with a person in another branch, located thousands of miles away and not connected to your network? The number of people who telecomute makes this feature very important. With LanTalk.NET, any person can be included.
