PBX Modules – Product Details & Advice
PBX modules are plug-in expansion units that increase the connection and channel capacity of a modular PBX. Common module types: a/b modules (additional analogue extensions), S0 modules (ISDN desk phones), VoIP modules (SIP channels), DECT modules (internal DECT base stations) and GSM modules (direct mobile network connection). Auerswald COMpact series (4000, 5020, 5500) and Agfeo systems are typical modular systems with vendor-specific slots. Always check compatibility with the system and installed firmware version.

Frequently Asked Questions
▶ How many VoIP channels do I need? As a rule of thumb: approx. 1 simultaneous channel per 5–8 employees (depending on phone intensity). A company with 40 employees typically needs 5–8 VoIP channels. For intensive use (call centre, sales), calculate rather 1:3. Include peak loads (Monday morning, promotional phases). |
▶ What is a GSM gateway module? A GSM gateway module connects the PBX directly to the mobile network (GSM/UMTS/LTE). Outgoing calls to mobile numbers are routed via the gateway SIM card – at mobile tariffs instead of landline-to-mobile prices. Useful for high outgoing mobile call volume. Incoming mobile numbers can also be routed to the system. |
▶ Firmware update for PBX – what to consider? Before a firmware update: fully back up configuration (manufacturer-specific backup tool). Read release notes – configuration changes may be required. Never apply update during core working hours (system restart). After update, test all functions (exchange lines, call forwarding, voicemail). Auerswald offers automatic update checking via the administration interface. |
