VoIP Compatibility with AT&T Arris BGW210-700: Disabling SIP ALG
The AT&T Arris BGW210-700 is a widely used gateway that offers a combination of high-speed internet and VoIP services. Despite its capabilities, users may experience issues with VoIP (Voice over Internet Protocol) functionality. A common cause of these problems is the SIP ALG (Session Initiation Protocol Application Layer Gateway) feature. This article explores the VoIP compatibility of the BGW210-700, highlights why it might not work properly with VoIP, and provides a guide on disabling SIP ALG to enhance VoIP performance.
The BGW210-700 is engineered to handle both internet and VoIP traffic.
However, its default settings, including SIP ALG, might not be optimized for all VoIP configurations.
SIP ALG is designed to assist with the routing of VoIP packets through the network's NAT (Network Address Translation).
It often disrupts VoIP communication, causing issues like call drops, one-way audio, or difficulty in registering VoIP devices.
Turning off SIP ALG can be a crucial step in resolving VoIP-related issues. Here are the steps to disable SIP ALG on the BGW210-700:
Connect to the Network: Make sure you're connected to your BGW210-700 network.
Enter the Router IP: Launch a web browser and input the default gateway IP, typically 192.168.1.254.
Log In: Enter your administrator username and password.
Navigate to Firewall Settings: Look for the 'Firewall' tab or section in the router's web interface.
Locate Advanced Firewall Settings: SIP ALG settings are usually found under advanced firewall options.
Identify the SIP ALG Option: Search for a setting labeled ‘SIP ALG’, ‘ALG Configuration’, or something similar.
Turn Off SIP ALG: Disable it by unchecking the box or switching the toggle to ‘Off’.
Save and Apply Changes: Make sure to save your settings.
Restart the Router: It's advisable to reboot your BGW210-700 to ensure the changes take effect.
Conclusion
VoIP issues with the AT&T Arris BGW210-700 can often be mitigated by disabling SIP ALG. While this feature is meant to facilitate VoIP communication, it frequently leads to operational problems. By adjusting the router's settings as described above, users can enhance their VoIP service quality, achieving more stable and clear voice communications.
