The diagram below illustrates the topology and a typical call scenario:

Topology

Before You Begin

Launch the WebUI and verify the node level settings:

1. In the WebUI, click the Settings tab.
2. In the left navigation pane, go to System > Node Level Settings
3. Verify that all the fields have been populated as indicated in the image below.
   Use the IP address from YOUR Primary Domain Server, not the sample IP address in the image.

Configuration Overview

The Sonus SBC 1000/2000 integration with the MS Exchange 2007/2010 Unified Messaging Server requires specific configuration steps to be completed using the WebUI to allow it to function properly in the topology described above.

1. Default Tone Table: A factory default

1. SBC

1. configuration contains the "Default Tone Table" entry. This article's configuration requires it, ensure its presence in your configuration.

1. Default Media Profile(s): the default G.711A/Mu-Law profile is used in this example.

1. Default Media List: the Default Media List is used in this example.
2. Create

1. a SIP Server Table: In this example we add a SIP Server table entry for the Exchange 2007/2010 Server.
2. Create

1. a SIP Profile: you can create a custom SIP Profile or use the default. The default is used in this example.
2. Create

1. a Transformation Table: this table is used in the relate Call Routing tables and for Called/Calling Number transformations.
2. Create

1. a Call Routing Table: in this example we create two table entries, one for ISDN and another for SIP. They are required in the relevant Signaling Groups.
2. Configure

1. a DS1 Port: this port is associated with the Physical PRI (T1/E1) connection.
2. Create

1. two Signaling Groups: One Signaling Group will be designated for for SIP and the other is for ISDN.
2. Set

1. the System Timing: you can configure the Clock Source to use the

1. SBC

1. system clock or a network source, depending on your PBX.

Configuring the

SBC

SIP Server Table

1. In the WebUI, click the Settings tab.
2. In the left navigation pane, go to SIP > SIP Server Tables.
3. Create a new *IP Server Table.
   The SIP Server Tables page is a table of SIP Server Tables.

4. Configure the new SIP Server Tableas shown in the illustration below.

Transformation Table

1. In the WebUI, click the Settings tab.
2. In the left navigation pane, go to Transformation
3. Add a new Transformation Table.
   The Transformation Table page is a table of Transformation Tables.

4. In the left navigation pane, click the Transformation table created in the previous step.

5. Add Calling / Called Party Number transformations to each one of these transformation rules as shown below.:

Transformation Rule to reach PBX Endpoints

Transformation Rule to reach PSTN Phones

Transformation Rule to reach SA/AA numbers

Transformation Rule to reach called party's voicemail (VM) box

Call Routing Table

1. In the WebUI, click the Settings tab.
2. In the left navigation pane, go to Call Routing Table.
3. Add an entry to the Call Routing Table. Name it Calls from ISDN (PBX).

4. Create two more entries. Name them Calls from Exch and Calls From PSTN.
   In this deployment, three call route table entries are required for the relevant Signaling Groups.

Route Table for Calls from PBX phones

This table requires two entries:

• One for routing calls to Redirected party's VM boxes in Exchange 20xx Unified Messaging Server (eUMS).
• Another one for routing the calls to 5xxx PSTN phones.

Route Table for Calls from Exchange Server

This table requires two entries:

• One for routing calls to 622x PBX phones via eUMS Auto Attendant or Subscriber Access prompts.
• Another one for routing calls to 5xxx PSTN phones via eUMS Auto Attendant or Subscriber Access prompts.

Route Table for Calls from PSTN phones

This table requires two entries:

• One for routing calls to 622x PBX phones.
• Another one for routing calls to 625x eUMS Auto Attendant or Subscriber Access numbers.

Port Configuration

1. In the WebUI, click the Settings tab.
2. In the left navigation pane, go to Node Interfaces > Ports
3. Click the expand () icon in the table next to the port used to connect the physical PRI line.

4. Complete the fields as shown below.
   Note that you will have to configure two Ports here, one for T1 connection to PBX, and another for T1 connection to PSTN, which will eventually be used in the relevant ISDN Signaling Groups

Signaling Groups

ISDN Signaling Group for PBX Connection

1. In the WebUI, click the Settings tab.
2. In the left navigation pane, go to Signaling Groups.
3. Click the Add ISDN SG text at the top of the Signaling Group Table.
4. Populate the fields as shown below.

5. Click OK.

SIP Signaling Group for Exchange 20xx Unified Messaging Server Connection

1. In the WebUI, click the Settings tab.
2. In the left navigation pane, go to Signaling Groups.
3. Click the Add SIP SG text at the top of the Signaling Group Table.
4. Populate the fields as shown below.

5. Click OK.

ISDN Signaling Group for PSTN Connection

1. In the WebUI, click the Settings tab.
2. In the left navigation pane, go to Signaling Groups.
3. Click the Add ISDN SG text at the top of the Signaling Group Table.
4. Populate the fields as shown below.

5. Click OK

System Timing Configuration

1. In the WebUI, click the Settings tab.
2. In the left navigation pane, go to System > System Timing.

3. Configure the Clock Source either as System or the Network, depending on your PBX timing settings.
   In this exercise, the Sonus SBC 1000/2000 node is reading the system time from the network therefore the configuration is done as shown below:

Signaling Group Status Verification

After having completed the configuration steps above, and the relevant configuration on Exchange 20xx Unified Messaging Server, verify the signaling group status:

1. In the WebUI, click the Monitor tab.

2. Verify that all three Ports come up as shown below:
