Flexible & Modular

Flexible Modular Design. Scalability Made Easy.

The telephony interfaces are fully modular and customizable. Add telephony modules, expansion boards and DSP modules to grow interfaces and system capacity as your needs change.

Telephony Modules

O2 — 2 FXO ports for 2 analog PSTN lines
SO — 1 FXS + 1 FXO for PSTN fallback
B2 — 2 NT/TE BRI ports
3G — 1 channel for voice calls
4G LTE — 4G cellular data on SIM card

Add Telephony Interfaces

For more interfaces, add expansion boards. EX08 offers 4 onboard module slots and 8 panel interfaces, while EX30 adds 1 onboard E1/T1/PRI port. The P560 supports one expansion board and the P570 supports two.

Expand System Capacity

As your business grows, add users and concurrent calls with ease. Each DSP module adds 100 VoIP users and 30 concurrent calls — up to 1 DSP module on the P560 and up to 2 on the P570.
