OfficeSIP Messenger

OfficeSIP Messenger is a free enterprise instant messaging software that offers advanced instant communication services to businesses. It is compatible with Office Communications Server 2007 and ensures reliable performance, along with trouble-free deployment and management. The software supports text, voice, and video chats, and implements ICE, STUN, and TURN protocols, which makes traversing NAT and firewalls easy. TLS support is also available to ensure ultimate communication security.

Unlike other enterprise instant messengers and communicators, OfficeSIP Messenger is completely server-based. As a result, administrators can easily manage and modify all settings, configurations, and user profiles from a corporate server. Single sign-on makes it easy for IM users to log in to the corporate domain, and Active Directory support allows the IM system to retrieve user information directly from the server's domain controller.

The software offers free voice calling using the SIP protocol, which makes it possible to communicate with recipients anywhere in the world. Single log-on enables softphone users to sign in to a SIP server without entering a password. Moreover, OfficeSIP Messenger provides businesses with advanced video chat capabilities, which can be installed efficiently and with zero-hassle NAT traversal.

With most offices using a single Internet uplink to connect with the world, sharing a single Internet connection often involves a NAT router. Combining a firewall with the router may prevent many voice communicators from streaming audio and video. Fortunately, OfficeSIP Messenger implements ICE, STUN, and TURN protocols to easily traverse NAT and firewalls without additional configuration on either side. TLS support ensures that all communications are securely encrypted and cannot be intercepted by a third party.

Overall, OfficeSIP Messenger is a free enterprise instant messenger that provides comprehensive and reliable services that are not found in its more expensive competitors.
