SIP Phone Support (SPS) can be offered as an appliance, running on the Open Solutions Network (OSN) Server within AudioCodes’ Mediant 800 or Mediant 1000, 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 an Enterprise SBC, Enhanced Media Gateway or Survivable Branch Appliance (SBA) for the Microsoft Unified Communications system.

SIP Phone Support for Microsoft Unified Communications - Applications

IP phones connected to Lync Server through SPS can be used as desktop phones 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 Microsoft^® Lync™ soft client or a Lync-compatible IP Phone.

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).

Third Party IP phone as desktop phone for Microsoft Lync

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

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