The IP Whitelisting feature allows customers to send calls directly from their PBX, SBC, or server to PBXME without registering to a SIP device. This is known as the Direct IP method. It is recommended for any customer using a static public IP.

If only one account uses that IP – only the IP field is needed.
If multiple customers share the same IP – a Prefix or X-Header must be added to differentiate traffic.
A single account can also whitelist multiple IPs if its traffic may originate from multiple servers.

Step 1: Navigate to IP Settings

Go to My Account → IP Settings from the top menu.

Step 2: View the IP Whitelist Page

Click on Create to add a new IP whitelist entry.

Step 3: Add the IP Details

Fill in the form fields as follows:

• Name – A label for your reference (e.g., Outgoing PBX).
• IP – The public IP of your server (e.g., 5.6.7.8). Use /32 for a single host.
• Prefix (optional) – A short numeric code to differentiate traffic when multiple users share the same IP.

• X-Header (optional) – A custom SIP header used for the same purpose (e.g., X-Header: ss44tt55).

Step 4: Save and Verify

Click Save. The IP will appear in the list showing the IP, Prefix, X-Header, and creation date.

Step 5: Notes

• You can whitelist several IPs for one account if calls come from different servers.
  • If an IP is already used by another account, you must define a unique Prefix or X-Header.
  • Once saved, calls from the whitelisted IP will be accepted automatically.
  • PBXME uses any Prefix or X-Header to identify which account each call belongs to.
