MP-11x & Microsoft Office Communications Server 2007
Quick Installation Guide 8 Document #: LTRT-26301
The AudioCodes' MP-11x FXO gateway can be integrated in the Office Communications Server
2007 / Unified Communications (UC) environments, by implementing one of the following options:
„ One-to-One: each PBX line connected to an FXO port on the gateway, serves one Office
Communications Server 2007 user / endpoint (OCS client) and is defined for automatic
dialing for this OCS client. A PBX or PSTN user that wants to call the OCS client, dials the
OCS client's PBX line number.
„ One-to-Many: group of PBX lines connected to the gateway serves all the OCS clients.
When a new call is received from the PBX, the gateway answers the call and performs one
of the following:
• Plays a dial tone, after which the caller can dial the OCS client's extension number.
• Plays a pre-recorded greeting message to the caller, requesting the caller to dial the
desired OCS client (for example, “Welcome company X, please dial the desired
extension number”). The gateway acts as an interactive voice response (IVR) system.
For this option, you may need to upload a pre-recorded tone file (refer the User's
Manual
).
„ PBX-Sends-Digits: group of Direct Inward Dialing (DID) PBX lines connected to the
gateway serves all the OCS clients. When a new call is received from the PBX, the gateway
answers the call, and then the PBX automatically sends the OCS client number as it was
received.
