OCS 2007 with Panasonic PBX TDA100

How simple is it for Panasonic PBX to move to IP base telephony platform via Microsoft OCS. We've successfully implemented Microsoft OCS 2007 with integration with Panasonic PBX model TDA100.

The situation is we've a requirement from the customer to remain the single line phone and its fax mahine as it is. Others user will be using the new OCS to makes voice call.

PBX information as followed:

Model: Panasonic TDA100 version 007-001

Region: 009-009

MPR (ML) card: 3.2002

PRI card: PRI30 version 2.009

The PBX is using two PRI (ISDN card), for incoming source from service provider and the second PRI card for connection to media gateway. The PRI card has to be enable QSIG signalling to communicate with the media gateway (as media gateway will require min. QSIG signalling). With this, the normal fax machine will still able to be connected to the PBX system.

During the implementation, the two connections (service provider and to media gateway) are require to use coaxial cable (with BNC connector as standard). Due to media gateway are having RJ45 connection only, we uses balun which conver the coaxial (BNC 75ohm) to RJ45 connection (RJ45 120ohm).

PBX is configured as slave as accepting the source from service provider and media gateway would need to be configured as master.
