The system can operate as a traditional key system or as a PBX system. The mode adopted by a IP Office Basic Edition system depends on the System SD card. Systems with an IP Office U-Law card default to key system operation. Systems with an IP Office A-Law card default to PBX system operation.
•This process can be performed through phone based administration from either of the first two systems in the system. For details, refer to the IP Office Basic Edition Phone Based Administration manual.
