How to turn off SIP ALG

Some 3rd party VOIP handsets may perform better when SIP ALG is disabled.


These steps are specifically designed for customers using the Sky Broadband Hub (SR203 & SR204). For further support using 3rd party handsets, please contact your supplier.


  • Make sure you're connected to your home broadband network
  • Open your browser and type into your address bar.
  • When prompted enter;
    • username: admin
    • password: <your WiFi password>
  • Select the Advanced tab followed by ALG in the sub-menu
  • Untick both boxes and select apply (read and accept notification)
  • Finally, switch your Hub off and on.

For more advice, ask the Sky Broadband community.
