Sangoma Express For Lync is all-in-one Lync server with a built-in VoIP gateway and SBC.Microsoft® Lync™ - Ultimate Unified Communications Solution which delivers complete presence, instant messaging, conferencing, easy-to-use interface and much more. Complexity rises when a Lync installation is integrated with the PSTN, either through traditional telephony interfaces or with a SIP Trunk.

Analysts agree that the Microsoft Lync is quickly gaining traction not only as a Unified Communications platform, but as a complete IP-PBX replacement. The initial release of Lync squarely focused on the large enterprise that had a complete staff of Microsoft Certified engineers or partners at their disposal. The complexity of a Lync installation had put implementation beyond the capacity of most SMBs. Complexity was increased when a Lync installation was integrated with the PSTN, either through traditional telephony interfaces or with a SIP Trunk.

To make Lync installations easy, Sangoma created Express for Lync: the only all-in-one Lync server appliance with a built-in VoIP gateway and Session Border Controller. The appliance is “right-sized” to support installations of up to 1,000 users with all the required software pre-loaded onto the appliance.
