This article will teach you how to set password-based or IP-based authentication for your SIP account.
By default, password-based authentication is enabled. However, you may want to switch to IP-based authentication when setting up a CommPeak server trunk.
To switch between authentication types:
Expand VoIP Services in the left pane.
Click the SIP Accounts tab.
Click Edit for the SIP account you wish to modify.
On the Edit SIP Account page, scroll down to the Authentication section. Depending on your choice, you can perform further actions.
IP-Based Authentication
Select the IP authentication option.
Enter one or more IP addresses allowed to access this SIP account.
To enter an IP address, type in the field and Add.
Click Save changes.
NOTE
For your SIP account, you can only apply IP authentication to static IP addresses. However, Cloud PBX and CommPeak Dialer users have more IP access options.
Password-Based Authentication
Select the Password authentication option.
Enter your username, which must be at least eight characters long. Optionally, you can add extra authentication with an IP ACL (access control list) — specify one or more IPs from which you can access the SIP account with these credentials.
Click Save changes.
