Requires Ribbon SBC1000/2000 Version 3.0
The following instructions detail configuring both Exchange 2013 and Ribbon SBC Edge to interoperate via TCP. It is suggested that any integration attempt begin with TCP and move to TLS, if required, only after ensuring the Exchange <> SBC connection is fully functional.
- Exchange = demo4.sbc.net (10.1.1.4)
- SBC = sbc2000.sbc.net (10.1.1.74)
Exchange 2013 Configuration
Use the following to configure Exchange 2013 to accept and process calls sent directly from SBC Edge.
Connect to the Exchange Admin interface via your web browser.
Select Unified Messaging.
Select UM dial plans.
Add a new UM dial plan. Add a dial plan to support the Exchange <> SBC connection.
Lync and PBX dial plans are different. You should not attempt to use a Lync dial plan to support the Exchange <> SBC connection.
Create a UM IP gateway. Create an entry in Exchange for the SBC gateway.
Modify the newly created UM dial plan.
Configure/verify Outlook Voice Access.
Add a UM Mailbox Policy to the dial plan.
Modify/verify the newly created UM Mailbox Policy.
Add a UM Auto Attendant.
Modify/verify the newly created UM Auto Attendant.
If a UM Hunt Group if a default does not already exist.
Add users to the newly created SBC dial plan. Adding extensions is accomplished via a user's Unified Messaging configuration.
Configure the SBC Edge
The next section covers configuring the SBC Edge to interface to the Exchange server.
Access the Ribbon SBC Edge WebUI.
Create/verify SIP Profile. Refer to Creating and Modifying SIP Profiles.
Create a SIP Server Table for the Exchange Server. Refer to Creating and Modifying Entries in SIP Server Tables.
Add the Exchange Server to the newly created SIP Server Table.
Create a Transformation Table and Transformation Entries to be used to process calls sent from Exchange's Subscriber Access (SA) and Automated Attendant (AA) to the SBC. Adjust your configuration according to your specific needs. Refer to Creating and Modifying Entries to Transformation Tables.
Create a Call Routing Table to process incoming calls from the Exchange SA and AA. Creating and Modifying Entries to Call Routing Tables.
Create a SIP Signaling Group to process incoming SIP calls from the Exchange Subscriber Access and Automated Attendant. Refer to Managing Signaling Groups.
Create entries in the Call Route Table. Refer to Managing Call Routing Tables. These call route entries process incoming calls from the Exchange Subscriber Access and Auto Attendant. Create a call route for every possible destination for Exchange SA/AA calls.
In addition to the above configuration that supports incoming calls from Exchange, you will need to create corresponding configurations to route calls to Exchange from other sources (such as PSTN and PBXs). It is strongly recommended that transformations for Exchange SA/AA appear at the top any transformation table. These entries not only handle the initial calls to Exchange, but also the 302 from Exchange (used during the call setup).
Not placing the Exchange transformations at the top of the transformation table may cause the 302 to fail, which will cause the calls to Exchange to fail.
When configuring for TLS, in Exchange Configuration, Step 5, change the SBC address to the SBC's FQDN rather than IP.
It has been reported that when a Exchange user has extensions for both Lync and direct-to-SBC dial plans that Exchange will send Message Waiting Indicator status only to the Lync extension. Exchange will not send MWI to a user's telephone extension when that user also has a Lync extension.
