Set Up IP-based Authentication for Outbound Calls
If your phone system has a Static IP address, we recommend using IP-based authentication for your outbound call authorization.
Have the following information ready before setting up IP-based authentication:
Your Flowroute Tech Prefix, found on your Account Profile page.
The list of IP addresses for which you want to set up IP-based authentication.
On your PBX phone server, configure your Flowroute Outbound Route to use the following outbound dialing format:
XXXXXXXX is your account Tech Prefix—for example, 12345678—followed by an asterisk (*), and
1NPANXXXXXX is the number to dial. This must be formatted first with the country code 1 (for North America), followed by the three-digit area code, NPA, and then the phone number, NXXXXXX. For example, 12066418000.
Your dial string should then resemble the following:
We have written guides for configuring outbound dialing pattern on the following:
- Follow the steps for statically routing your inbound calls to your Public IP Address.
Repeat the steps above for each PBX phone system that you are using.
IMPORTANT: For your security, we recommend using IP-based authentication exclusively by disabling SIP credentials for outbound calls in Flowroute Manage. This change will restrict outbound calls on your account to complete only from your Outbound Allowed IPs. To make this change, go to Preferences > Fraud Control in Flowroute Manage. In the top section of this page, click Disable Credentials.
