The Carrier application provides tools to configure advanced settings and priorities for managing multiple carriers. This is often based on unique circumstances and services a carrier does (or does not) support. In some countries for example, local less expensive carriers may limit the area of their calls and either not allow or charge extra fees to make calls outside that area. Carriers allows you to add settings to define where call types may be directed.

Use Cases

• My carrier / 911 Provider is asking me to include a specific DID number in the SIP header for all 911 calls. How do I do this?
• I company who have a local and Toll Free number, but my Toll Free has some fax issue so we want to route all calls going to Toll Free to the local number.
• Carriers in Canada just allow to call within provinces. (i.e. Toronto to Quebec, send fax to a toll-free). Route calls going outside their province using a different carrier.

911 directs to a dedicated DID

A few dedicated 911 providers (such as Northern 911) use their own system to handle 911 calls, and will provide their clients with a dedicated DID phone number to include in the SIP header of all 911 calls.

Based on these requirements, the syntax sent to the e911 dispatcher would change

From (2600Hz default):           911@carrier, from: emergency_did@customer_realm

To (designated by 911 provider):     customer's_account_911_did@northern
