Dialogic® Media Gateways can link a traditional PBX or PSTN voice circuit to new VoIP solutions such as Microsoft® Ofﬁce Communications Server 2007. They are designed and tested to be easy to deploy, easy to manage, and to provide reliable operation. This guide provides instructions for installation and conﬁguration of the Dialogic® 2000 Media Gateway Series (DMG2000).

Ofﬁce Communications Server 2007 Environment.

STEP

Trunk Preparation

The PBX-side T1 or E1 trunk must be conﬁgured for T1 (NI2, QSIG, 5ESS or DMS protocols) or E1 (Euro ISDN or QSIG protocols). For more information on PBX programming, refer to: http://www.dialogic.com/microsoftuc/ocs_integration.htm

Cabling Requirements

Cabling for T1/E1 ISDN Connections must be CAT5e or better. A T1/E1 crossover cable may be needed depending on the PBX. See Table 1 for the connector pin designations.

Pin Description

1 RCV_RING

2 RCV_TIP

3 No Connection

4 XMIT_RING

5 XMIT_TIP

6 No Connection

7 No Connection

8 No Connection

Table 1. T1/E1 Connector Pin Designations

STEP

1. Unpack gateway.

2. Connect T1/E1 cables to rear panel.

3. Connect power cord.

4. Turn on power switch.

STEP

There are two options for performing the initial conﬁguration of the gateway -serial or IP.

Connecting with Serial Port

1. Connect a DB9 serial cable to the COM 2 port on the gateway.

2. Establish a connection to the gateway (Baud=115200, Data Bits=8, Stop

Bits=1, Parity=none, Flow Control=none) using a terminal emulation program (e.g. HyperTerminal). See Table 2 for the serial port pin outs.

Table 2. Serial Port Pin Outs

Connecting with Ethernet

1. Connect gateway to Network using LAN 1.

2. Conﬁgure computer connecting to gateway on the 10.12.13.x subnet

(e.g. 10.12.13.75) and subnet mask of 255.255.255.0.

3. Use Telnet and connect to gateway at: 10.12.13.74.

Initial Gateway Conﬁguration

1. Conﬁgure initial gateway. Press Enter key until you get to the “PIMG”

prompt. Follow the steps below and modify the settings in red to match your environment. The values in bold are what you will be entering.

PIMG> pwd Enter Password: IpodAdmin Admin level accepted. PIMG-admin> quickcfg LAN 1 IP Address[10.2.2.3] : (Enter new IP Address that

matches gateway IP Address entered in Mediation server)

LAN 1 Subnet Mask[255.255.255.0] :

(Enter new Subnet Mask)

LAN 1 Default Network Gateway Address[10.2.2.5] :

(Enter new Default Network Gateway Address)

LAN 2 IP Address[10.2.2.2] : LAN 2 Subnet Mask[255.255.255.0] : Select Line Mode ... Valid entries:

1. T1

2. E1 Enter Number for Line Mode Selection [T1] : 1 Select Protocol ... Valid entries:

1. CAS - Loop Start

2. CAS - Ground Start

3. CAS - E&M Immediate

4. CAS - E&M Delay

5. CAS - E&M Wink

6. ISDN - QSIG

7. ISDN - NI-2

8. ISDN - 5ESS

9. ISDN - DMS-100 Enter Number for Protocol Selection [ISDN - NI-2] : 6 Saving parameters now...

Parameters successfully congured!

******* Restart Required ******* (Type ‘restart’) PIMG-admin> restart rebooting...

2. Clear ARP Table on computer connecting to gateway (e.g. on Windows-based

machine, the command is “arp -d*” from a Command Shell).

3. Change the IP address on computer connecting to gateway to match the

newly conﬁgured gateway IP subnet.

STEP

– FINAL GATEWAY CONFIGURATION

Once the initial conﬁguration is complete and the gateway has been reset, you will need to log into the web interface by browsing to the IP address of the gateway using “admin” as the user and entering the gateway password (“

IpodAdmin”

is the default).

Setting T1/E1 Parameters

Navigate to: Conﬁguration > TDM > T1/E1 and adjust the following settings -

1. Set Telephony Port Interface Side: This should be Terminal if your PBX is set to Network or Network if your PBX is set to Terminal.

2. Set Line Encoding and Framing: This should match your PBX settings.

3. Click Submit to save settings. This will prevent loss of conﬁguration. Do not restart the gateway.

Set Telephony Port Interface Side to Network or Terminal, using the opposite setting from your PBX setting

Set Line Encoding and Framing to match your PBX settings

Navigate to: Conﬁguration > TDM > General and adjust the following settings -

1. Set PCM Coding: uLaw or aLaw to match your PBX setting.

2. Click Submit to save settings. This will prevent loss of conﬁguration. Do not restart the gateway.

Set PCM Coding: uLaw or aLaw to match your PBX setting

Setting Microsoft® Ofﬁce Communications Server 2007 Speciﬁc Parameters

Navigate to: Conﬁguration > VoIP > General, and adjust the following setting -

1. Set Transport Type: TCP.

2. Click Submit to save settings. This will prevent loss of conﬁguration. Do not restart the gateway.

Set Transport Type: TCP

Navigate to: Conﬁguration > VoIP > Media, and adjust the following settings -

1. Set Audio Compression: G.711u or G.711a to match your Microsoft® Ofﬁce Communications Server 2007 setting.

2. Set Signaling Digit Relay Mode: Off.

3. Set Voice Activity Detection: Off.

4. Set Fax IP-Transport Mode: G.711-Passthrough.

5. Click Submit to save settings. This will prevent loss of conﬁguration. Do not restart the gateway.

Navigate to: Conﬁguration > Routing Table, and adjust the following settings -

1. Select VoIP Host Groups radio button.

2. Enter your Microsoft

Ofﬁce Communications Server 2007 Mediation Server IP Address in the Host List ﬁeld.

3. Click Submit to save settings. This will prevent loss of conﬁguration. Do not restart the gateway.

Select VoIP Host Groups radio button

Ofﬁce Communications Server 2007 Mediation Server IP Address in the Host List ﬁeld

STEP

For the conﬁguration changes to take effect, you will be prompted to restart the gateway. Select the Restart menu option through the web interface and proceed to click on Restart Unit Now.

After restarting the gateway, examine the T1 link in front of the gateway and make sure that the T1 LED is green. If it is yellow or red, please check your cable and gateway T1 conﬁguration or consult with your PBX vendor. Once you have a green LED, you can begin making PSTN to Microsoft® Ofﬁce Communications Server 2007 calls if Normalization rules were conﬁgured for inbound PSTN calls. Microsoft® Ofﬁce Communications Server 2007 to PSTN calls would require more rules to be added.

STEP

Conﬁguring calls from PSTN to Microsoft® Ofﬁce Communications Server 2007

No modiﬁcations to the Inbound TDM Rules under the Routing Table are needed if Microsoft® Ofﬁce Communications Server 2007 is conﬁgured with Normalization rules for inbound PSTN calls.

Note: Microsoft recommends that Normalization Rules be completed within the Microsoft® Ofﬁce Communications Server 2007 conﬁguration. If however, Normalization is not completed there, then new rules have to be added to the Dialogic® 2000 Media Gateway Series for calls from the PBX to the Microsoft® Ofﬁce Communications Server 2007 environment. For information on conﬁguring Normalization Rules on the Dialogic® 2000 Media Gateway Series, refer to:

http://www.dialogic.com/microsoftuc/OCS_DMG2000_setup_6x.pdf

Conﬁguring calls from Microsoft® Ofﬁce Communications Server 2007 to PSTN

Gateway Inbound VoIP Rules need to be added in order to convert E.164 formatted numbers into numbers that can be dialed by the PBX.

Routing Rule Examples can be found in the following documents:
