To make VoIP calls, you will need a SIP account provided by the SIP Proxy you are

registered with. To configure the relevant SIP settings, please refer to the instructions

explained below.

3.3.1 PABX Mode (Micronet SP5018A)

This quick setting is dedicated to be used for Micronet SP5018A to become a

inter-connection in between PSTN and traditional PABX. The call scenario will be working

as below:

1. For FXO incoming call, it will route to corresponding FXS directly (1 by 1)

2. For FXS outgoing call, it will route to VOIP except those prefix set in FXO dialing

Prefix.

3. For VOIP incoming call, it will route to FXS based on the called number

4. When VOIP call is failed to be called out such as register fail or network issue, the

call will be route to FXO as backup.

5. When Micronet SP50X8A is malfunction or power failure, the all call will be directly

bypassed to FXO.
