Hey thanks for the information. I've deactivated that one. Now it works. But why not. I'm forwarding now only the ports that are really needed and my phone don't need to do STUN for no reason.

Any reason why your SIP traffic is tagged 26 and not 24? Is that something that can change from provider to provider?

The first few sections will cover the basis of disabling SIP ALG and SPI for higher-class enterprise devices while the lower sections relate to common devices used in small offices or homes. If running a business class Cisco router, you can initiate a terminal session with an application like PuTTy or directly accessing the console.

If it worked, the next line displayed after the "do show" command will read "no ip nat service sip tcp port " and "no ip nat service sip udp port ".

Access the console and enable elevated privileges. Enter the following commands to turn of SIP inspection at a global level.

If keen to learn and experiment with Cisco solutions, I suggest using the emulator furnished by GNS3. However, such configuration techniques are far beyond the scope of this article. If the ASA at your business is manageable by this client, the following techniques should prove to be an easier way for accomplishing the same task compared to the command line techniques described in the previous section. Note that this will apply a global setting to your entire device.

For port specific settings, navigate to the settings for each port and alter if necessary. Like Cisco, slightly different interfaces are common, relative to the version and model of the system.

Figure 2 shows an example of the SonicWall user interface on the page where these settings exist. Understand that although this method seems quite generalized, it is the basis for disabling SIP intervention on most SonicWall systems.

Netgear has several different interfaces. As this brand is one of the most popular for home and small business networking, variation in interfaces is common due to the large number of devices made by the company. However, the following example should provide a good reference for the more common models and show you how to disable SIP ALG on your Netgear router. Check the box, apply the settings and reboot if prompted.
