Proactive Traffic Rules
Proactive Traffic Rules are a great way to protect your Vonage account against abuse. We recommend that you review and set up these rules in advance.
Vonage has applied a default set of rules blocking certain high-risk destination countries, which are listed below. You can use "allow" rules to override these "block" rules.

Here are some rules you can set:
- Create "block" rules based on country codes or phone number prefixes, e.g., +44 (UK) or +447 (UK Mobile).
- "Block" or "allow" rules may be created for individual phone numbers. You can block a single mobile number, for example
+447970123456, or a smaller range, such as the network prefix447970. - "Block" and "allow" rules may be layered. Rules that match a larger set take priority, and where there is a tie, "allow" rules take precedence.
Here is an example with number 1 being most prioritized:
- Block
447970123456(apart from this specific number, which must be blocked) - Block
44(the UK) - Allow
447(except UK Mobile numbers, which are allowed)
You may view all captured traffic from the alerts section.
