Explanation of the gateway number

Gateway Numbers in Onoff Calls

When making calls with your Onoff number, you may occasionally notice a temporary number appearing on your screen before the call connects. This is called a gateway number, and it’s a normal part of how Onoff routes calls.

Understanding this process helps clarify why it appears and why there’s nothing to worry about.

How Gateway Numbers Work

A gateway number is a temporary technical number used by an Onoff server to establish the connection between you and your contact.

It may briefly appear on your screen while the call is being set up. Once the connection is established, the call continues normally.

This number is part of the internal call routing process and is not meant for user interaction.

Why It Appears During a Call

Onoff uses secure servers to route calls between users and the telecom network. The gateway number acts as a bridge that connects your Onoff number to the destination number.

Seeing this number simply means the call is being routed correctly through the Onoff infrastructure.

What Your Contact Sees

Your contact will never see the gateway number.

They will always see your Onoff number as the caller ID, exactly as expected. The temporary number is only part of the internal connection process and is not visible to the person you are calling.

Impact on Call Quality and Billing

The presence of a gateway number does not affect:

• Call quality
  
• Billing
  
• Caller ID display
  
• The way the call works overall
  

It is purely a technical step in the background.

Key Points to Remember

• A gateway number may appear briefly when you place a call.
  
• It is used by Onoff servers to connect the call.
  
• Your contact will always see your Onoff number.
  
• It has no impact on quality, billing, or functionality.
  

In short, seeing a gateway number is completely normal and simply means your call is being connected as intended.
