If you have an existing investment in legacy business communications systems (PBXs and key systems), UC Server lets you leverage your existing investment and transition from legacy telephony to IT Telephony at your own pace. With its multi-PBX support, UC Server can provide all its unified communications features both natively on UC Server and on your legacy PBX.
