Flexible Modular Design.
IP PBX Scalability Made Easy.

The telephony interfaces are completely modular and customizable. Use telephony modules, expansion boards, and DSP modules to easily add more telephony interfaces and expand system capacity.

S2 Module: 2 FXS ports to connect 2 analog telephones

O2 Module: 2 FXO ports to connect 2 analog PSTN lines

SO Module: 1 FXS port and 1 FXO port for PSTN fallback

B2 Module: 2 NT/TE BRI ports

GSM/3G Module: 1 channel for GSM voice calls

4G LET Module: Enable 4G cellular data on SIM card

To add more telephony interfaces, go for the expansion boards.

EX08 has 4 onboard module slots and 8 interfaces on the panel, while EX30 has 1 onboard E1/T1/PRI port.

P560 supports one expansion board and P570 allows two.

As your business expands, more uses and concurrent calls can also be added easily to meet growing needs.

Each DSP module gives you an extra 100 VoIP users and 30 concurrent calls, and you can add up to 1 DSP module to your P560 and up to 2 DSP modules to your P570.
