Disabling an ALG on your router may well help with any VoIP problems. Here are some notes on various routers that we've come across:
== ZyXEL VMG1312 and VMG3925 ==
Usually disabled by default.
*Log in to the router's web interface
*Go to:
**Network Setting - NAT - ALG
*Disable the settings there
== Technicolor ==
To completely disable the SIP ALG, you will need to connect via Telnet to your router.
:connection unbind application=SIP port=5060
:saveall
:exit
(On older models/firmware the command to use is '':nat unbind...'' rather than '':connection unbind...'')
==Billion 7800==
== Neatgear==
From Wan Setup Menu: go to NAT Filtering and
==Vigor2750, Vigor2130==
If SIP ALG is disabled successfully, it will show Nat Sip v2 switch off! This will reset when rebooted and will need to be set again.
