The new multi-service QuesCom Gateway

By integrating ISDN, GSM and IP, the QuesCom 400 Evolution enables:
-    Redundancies between the links
-    Multi-network routing (SIP, GSM, ISDN, IP…)
-    Multi-protocol commutation and SIP commutation, like in a Microsoft Lync environement
-    Voice and data channels aggregation

Voice and data services continuity are secured through powerful routing rules. When the internet link gets down, the gateway dynamically switches toward mobile network (2G, 3G or 4G) ; reaching several Mb/s thanks to mobile channels aggregation.


Embedded applications

The QuesCom 400 Evolution offers feature rich options:

- Fax Server (with single number reach)
- Mobility Server
- Presence Server
- SMS Server
- Wireless IPBX
- Voice and Data backup router

ISDN, VoIP, and GSM equipment

PBX connection:

• In pass-through on ISDN links
• In IP

Cluster: a group of devices can be managed as a unique system. Qasaar architecture enables a unified view of the deployed systems.


VoIP convergent gateway, SIP commutation


For a single site enterprise, QuesCom 400 Evolution interconnects VoIP operators in order to make a SIP Trunk. For a multisite enterprise, QuesCom 400 Evolution interconnects all sites in IP. The enterprise can smoothly migrate to IP without changing its existing architecture.

QuesCom 400 Evolution perfectly fits to heterogeneous PBX environments (IPBX, legacy PBX, Microsoft Lync…).
