Using the Gateway Computer Between the PSTN and

PBX/Microsoft® Office Communications Server 2007

This configuration scenario describes the necessary steps if the gateway computer is

connected between the PSTN and PBX/Microsoft

Office Communications Server 2007. This

way, Diva SIPcontrol can also route calls from the PBX to the PSTN, and vice versa. One PRI

line is connected to the PBX and one PRI line is connected directly to the PSTN. This

scenario also assumes that the PBX was previously connected to the PSTN directly and the

PBX has not been reconfigured at all to cope with any changes introduced by the gateway or

Microsoft

Office Communications Server 2007.

The Microsoft

Mediation Server is installed on the gateway computer. The PBX is

configured for the extensions starting with 2 or 3, and the Microsoft

Office Communications

Server 2007 is configured for the extensions starting with 4 or 5. Diva SIPcontrol expects a

PSTN access code in calls from Microsoft

Office Communications Server 2007 to the PSTN

or from the PBX to the PSTN; in the following example, it is an additional 0 (zero). Diva

SIPcontrol is configured to remove the access code before forwarding the call to the PSTN.

For convenience, Diva SIPcontrol is also configured to add the outside access code to the

calling number in calls coming from the PSTN. Since the PBX is not aware of the presence of

the gateway and Microsoft

Office Communications Server 2007, it does not send or expect

to receive any outside access code. Therefore, Diva SIPcontrol also removes the outside

access code in calls to the PBX and adds it in calls from PBX.

For this configuration scenario, one dialplan, five address maps, the two PSTN interfaces,

the network interface, two SIP peers, and five routes need to be configured.

Open the Diva Configuration Manager. To do so, click Start > Programs > Dialogic

Diva > Configuration Manager.

Click the line icon for port one and under Operation Mode set TE-NT Clock

Synchronization to Yes:
