Home - VoIP Service - What is SIP ALG and Why VoIP Users Should Disable It? An In- Depth Look
Reviewed by : Prasanta Raut
VoIP (Voice over IP) has grown into an essential tool for efficient interaction in the connected world of today allowing efficient and open interactions for people as well as businesses. Despite its benefits, VoIP users run through irritating issues that can ruin their experience.
The Application Layer Gateway for the Session Initiation Protocol is one of the major culprits behind these issues. SIP Address Translation (SLG) initially emerged to help SIP traffic negotiate Network Address Translation (NAT) devices however it often creates more issues than it fixes.
SIP ALG, which is found in a lot of routers and firewalls, alters the headers of SIP packets to help them go outside NAT. But instead of providing smooth communication, SIP ALG often causes problems like poor call quality, one-way audio and lost connections.
We’ll dive into what is SIP ALG and, how it works, and why turning it off can improve your VoIP experience in this blog post. We’ll also go over best practices for keeping your VoIP setup dependable and effective.
Let’s explore how to get over these challenges to improve your communication!
Table of Content
The Session Initiation Protocol Application Layer Gateway is referred to as the SIP ALG. This works inside the OSI (Open Systems Interconnection) model at the application layer. This ability is present in a majority of business gateways to support stable connections.
Users can start SIP calls simply with the help provided by the SIP ALG that works in the customer-side LAN gateway, and functions as a distinct software. After that, the VoIP audio messages are sent out through the internet. Although the objective of this technique is to improve call quality, it usually falls low.
It is vital to know the mechanics of SIP ALG to be able to understand why it can be harmful. SIP packets are monitored and modified by SIP ALG while they are passing through NAT devices. This is a detailed breakdown of how it works:
If SIP ALG interferes with your VoIP calls, there are many clues. These are a few of the most popular ones:
Turn off SIP ALG and check your router’s settings if any of these are happening to you. Before we discuss how to accomplish that, let’s examine the reasons behind the need to disable SIP ALG.

1. Use the CLI interface to execute the following commands:
configure system session-assistant

2. Locate the SIP session instance that #12 refers to.
3. Subtract #12 or the relevant number.
4. Use this command to verify that it has been erased:
Disabling the SIP ALG in a VoIP profile is the second technique. Should you be utilizing the SCCP VoIP profile, use the following command:
Configure VoIP Profile
Edit VoIP_Pro_2
Configure SIP

According to traditional knowledge, an Application-Level Gateway has to be switched on. Eventually, a lot of residential and commercial network settings even have SIP ALG enabled by default to on.
Most internet routers have SIP ALG activated which was created in order to solve some of the problems of network address translation (NAT). However, it blocks IP and signal systems’ natural working, making them unnecessary for modern VoIP systems.
Since ALGs work at the OSI Model’s Application Layer, they are incapable of taking into consideration datagrams included in transportation protocols like TCP or UDP. VoIP signaling techniques include a both public and private internet address in every data packet to get around these common problems.
A “security system keyhole” is a security flaw that certain routers try to eliminate by closing open connections within the firewall. This allows traffic to move for brief periods but once VoIP calls are formed, they can become unstable due to packet drops from SIP gateways.

Reliable VoIP performance needs a combination of network optimizing, equipment setup and supervision. Here are a few best practices to ensure unchanged and high-quality VoIP efficiency:
We highly recommend using Quality of Service ( QoS ) to create network choices once you reach about 15 users. By using VLAN tagging, VoIP data can be given priority over less significant network traffic. This method improves the overall safety of your VoIP system and reduces the loss of packets.
Disabling SIP ALG is a frequently ignored yet very useful solution for many more common VoIP call issues. Even seasoned operators often overestimate this small adaptation, yet it can greatly improve the reliability and standard of your virtual phone service.
If you’re reading this because your phone system causes you trouble, know that you’re not the only one. It could be interesting to work together with a reputable VoIP provider instead of trying to solve these problems on your own. Technical difficulties can be solved more easily with expert help, ensuring a smooth communication experience.
Ethernet offers a more stable and rapid connection than wireless, decreasing jitter, delay as well as package loss which are essential to VoIP discussion that is high quality. In comparison with wireless configurations, Ethernet ensures VoIP devices an ongoing throughput and enhances security by requiring physical access to the network which reduces the risk of spying.
Ethernet is a better choice for businesses handling private information due to its easy control and reliability which lowers expenses for upkeep and outages.
Remain alert by routinely checking the manufacturer of your router for firmware upgrades. These upgrades may reset some settings but they can also fix safety issues and improve performance.
It might be required by you to apply software upgrades on industrial devices through the Command Line Interface (CLI) or obtain updates from the vendor’s FTP site. You can be sure you’re always current by talking with your supplier.
In conclusion, VoIP services are frequently disrupted by SIP ALG (Session Initiation Protocol Application Layer Gateway), a router feature intended to help with network address translation. This results in problems like dropped calls and one-way audio.
Enhancing VoIP reliability involves mainly removing SIP ALG. Essential things to consider are selecting a suitable ISP, using wired connections, placing VLAN tagging into action and upgrading router firmware. If problems persist, talking with an expert VoIP provider will assist ensure reliable and transparent communication.
Disabling SIP ALG is an excellent choice because it often interferes with VoIP communication resulting in problems such as interrupted calls, one-way audio and lost connection. By switching it off, VoIP service can be more reliable and consistent without forcing networks to change unnecessary messages.
The regular movement of SIP packets among VoIP devices and services could be interrupted by SIP ALG. It often modifies these data packets accidentally which causes issues in communication. For instance, it could change private IP addresses to a public one which could give rise to problems when trying to connect to VoIP services.
In numerous instances, SIP ALG needs to be disabled in order to ensure that VoIP calls work properly. SIP ALG is an usual cause for VoIP problems frequently leading to issues like dropped calls, one-way sound or phones never ringing through. Its disability can help reduce these problems.
SIP (Session Initiation Protocol) handles the beginning, halting and managing of video and audio calls over the internet. In order to ensure that communication sessions are properly organized and controlled, it handles call set up, sessions modifications and call termination. Since SIP enabled features like hold, meeting, and call transfer feasible, it is essential to dependable and efficient VoIP communication.
ALGs are used to facilitate network traffic traversal across NAT (Network Address Translation) devices by handling specialized application protocols.
