sipXcom
sipXcom provides complete enterprise-grade telephony, unified messaging, Instant messaging, audio conferencing, and many other features. sipXcom can be run along side your existing Cisco, Avaya, Mitel, Shortel or other PBX while you migrate users to the sipXcom system. In addition to running sipXcom on a server or cluster of servers (this can be a virtual or cloud environment), sipXcom supports standards-based SIP desktop phones, soft clients, gateways, SBCs and runs in an IP-based switched network infrastructure. If you are not ready for a complete migration or if you would like to add or enhance your existing voice capabilities, sipXcom is modular and can be integrated with your current system to add a variety of features such as unified messaging, vmail, audio conferencing, and instant messaging/chat.
