Net2phone firewall configuration
If you are experiencing poor call quality or dropped calls with your Net2phone hosted phone system, several factors could be contributing to the problem. The most common issues are often related to your Internet Service Provider (ISP), including latency and packet loss. Another frequent problem might be related to your firewall configuration. Your firewall plays a critical role in handling your voice traffic, and if it's not configured correctly, you may encounter these issues.
To ensure the best possible experience with your Net2phone services, please make sure to adjust your security policy and configuration accordingly.
You may also access specific guides for the specific firewall you use below. If you use another firewall, please implement the rules outlined in this article.
