CGW-I Tell a Friend

CGW-I BRI to GSM Cellular Gateway*

Cut your business phone costs by connecting your ISDN telephone system directly to GSM cellular networks.

The CGW-I is a BRI to GSM Cellular Gateway that lets you call cellular numbers from your ISDN telephone system, benefiting from low business tariffs, bypassing your landline carrier and eliminating interconnection fees.

The CGW-I is your transparent and low cost solution for calls to GSM mobile phones:

  • Fast ROI (Return On Investment)
  • Available with 2 GSM channels

Incoming and Outgoing Call Features

Intelligent Routing – Return up to 1,500 mobile calls directly to the calling DDI (Direct Dial-In). CGW-I stores the link between the dialing extension and the dialed cellular number. When a missed mobile call is returned, CGW-I recognizes the Caller ID and routes the caller to the dialer’s extension.

Call Barring – Dedicate your SIM to handle only incoming calls, outgoing calls, or both.

Call Diversion – Automatically reroute incoming calls to an alternate channel when SIM is busy.

Toll Restrictions – Define which cellular operator prefixes to allow the CGW-I to call and which ones not to allow.

Redirect Calls – Override Toll Restrictions and set up a cross-network connection.
