SIP Phone Support for Microsoft Unified Communications

SPS enables the connection of the 300HD Series with Microsoft Office Communications Server, while providing Office Communications Server features, such as enhanced presence, active directory, and support for Real Time Audio (RTA) - Microsoft’s high-definition, wideband coder.

SPS can also be used to enable connectivity and provisioning of AudioCodes certified third-party SIP IP Phones from leading vendors, such as Cisco and Avaya, providing IT managers with full investment protection for their IP Phones.

SPS can be offered as an appliance, running on the Open Solutions Network (OSN) Server within AudioCodes’ Mediant 1000 or Mediant 2000, or alternatively, as a standalone server that uses external DSP resources on the AudioCodes gateways, in case they are required. The AudioCodes gateways hosting the SPS service can simultaneously function as a “Basic” or “Enhanced” Media Gateway for the Microsoft Unified Communications system.

SIP Phone Support for Microsoft Unified Communications - Applications

IP phones connected to Office Communications Server through SPS can be used as a desktop phone for Microsoft Office Communications Server, for locations without PC workstations or for users that prefer the convenience of using a phone handset.

Making and receiving calls using the IP Phone updates user presence just like using Office
Communicator.

The user can change presence status and search for contacts from the phone directly. The user’s contacts presence can be displayed on the phone. (requires BLF support from the SIP phone).

Alternatively, an IP Phone connected to Office Communications Server through SPS can work in conjunction with Microsoft Office Communicator. This mode combines the best of both worlds: the ability to make convenient voice calls from the desk phone, together with Office Communicator’s advanced features such as Instant Messaging.

In this case, incoming calls will simultaneously be received at both the IP Phone and Office Communicator, giving the user the ability to pick the call wherever it is more convenient. Presence is updated in all of the user’s devices.
