Hybrid Telephone Systems – Product Details & Advice
Hybrid telephone systems combine analogue (a/b), ISDN (S0/S2M) and VoIP (SIP) interfaces in one device and are ideal for companies transitioning from ISDN to all-IP. They allow simultaneous use of ISDN system phones, analogue terminals and SIP IP phones on a shared PBX without additional gateways. Auerswald COMpact 5020 VoIP and Agfeo ES 516 IT are typical hybrid systems for small to medium companies (up to 30 extensions). SIP trunking capability enables operation via all-IP lines while ISDN system phones can continue to be used.
ISDN system phones: ISDN System Phones. IP system phones: IP System Phones. Advice: sales@industry-electronics.com.
Frequently Asked Questions
▶ Which hybrid system do you recommend for 20 extensions? For 20 extensions (mix of ISDN, analogue, SIP), we recommend the Auerswald COMpact 5020 VoIP (up to 20 extensions, expandable) or the Agfeo ES 516 IT. Both support ISDN S0, analogue a/b ports and VoIP channels simultaneously. For >30 extensions, larger Auerswald COMpact series are suitable. |
▶ Can a hybrid system be fully switched to SIP? Yes – most hybrid systems can be gradually switched to pure SIP operation. ISDN interfaces then remain unused (but can be reactivated at any time). For a complete transition to IP telephony without ISDN legacy, pure IP PBX systems are recommended. |
▶ Do hybrid systems support voicemail and auto attendant? Yes, modern hybrid systems have integrated voicemail functions (often as an optional software licence). Auto attendants (IVR, Interactive Voice Response) route callers via voice menu to departments. Extensions such as CTI server (TAPI) and UC software are connected via manufacturer-specific apps (Auerswald myApps, Agfeo Phonemanager). |
