3.0.0.4.334 firmware killed my SIP telephony and no ALG setting.

RMerlin... could I ask how you knew about the telnet command? Is there a list somewhere for what settings, etc, are available via telnet on this router?

I know about it because I have been developing a custom firmware for the RT-N66U and RT-AC66U for the past year, so I'm fairly familiar with the source code. Toggling the state of the SIP helper is something I have added to my webui a few months ago, specifically for the issue described here.

Thanks rmerlin for the solution. Works for my a580ip Siemens phone. Almost wanna give up on this newly purchased router.

Running 3.0.0.4.270.26 firmware.
When tried to use SIP in android devices the audio did not came from outside.
After issuing set nf_sip=0 everything started to work perfect.
Thanks for solution.
