Ive got a technicolour tg582n pro router that ive disabled SIP ALG on (as per my voip providers request).
To do this on this model of router i followed this guide online where you telnet into the router run a command (although it has a browser based dashboard SIP ALG isn't accessable from there), i believe I've disabled it correctly as i didn't get any error message up when doing it, but cant be 100% sure.
Is there a test i can do to check is SIP ALG is disabled on my router ? Ive found some online Java applets that seem to test this but when ever i click to use them they all need complete access to the computer to run, which im not happy doing as i have know idea who these sites are. Is there another way it can be tested either through a telnet query or somthing similar ?
