Microsoft will open up beta versions of its unified communications server and client software to the public for download on Monday, a senior company executive said Wednesday.

The release includes Office Communications Server 2007, its VoIP server software, and Office Communicator 2007, an application for mobile devices, said Gurdeep Singh Pall, corporate vice president for Microsoft's real-time collaboration product group.

The server is Microsoft's entry into the enterprise Internet telephony business, where it hopes to replace traditional PBX systems as well as displace IP PBX systems from vendors like Cisco and Avaya.
