How to add analog trunks?
The number of Analog trunks (i.e. FXO ports) is determined by the number of O2 modules (one O2 module contains two FXO ports, i.e. 2 analog trunks) and SO modules (one SO module contains one FXO port, i.e. 1 analog trunk) installed in MyPBX. So if you need to add analog trunks, please make sure that there remain module slots for O2 or SO module first.
- Power off or unplug MyPBX.
- Unscrew MyPBX, and open the upper case.
- Insert the O2 or SO module into the corresponding slot and place back the upper case and tighten the 4 screws. Then power on MyPBX and new analog trunks will be added successfully after rebooting.
