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.

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.

You can disable the SIP helper by running these commands over telnet:

Code:
nvram set nf_sip=0
nvram commit
Then reboot the router to apply the change.

Not sure they will help in your case (I keep it enabled here).
I have Elastix v2.4.0 and I had no audio issue when connected remotely via android Zoiper app. After disabling this I can hear again Thanks!

Hey Merlin, quick question (sorry to bump an old thread). Is the sip helper you toggle from CLI the same as the SIP Passthrough that's in the Web GUI (Advanced / WAN / Nat Passthrough)?

I've been deploying hosted pbx service for a long time, and this is the first time using a dark knight. When I disable sip passthrough, I cant get the phones to register to our SBC, but with it enabled, they register. I just know that in general ALG causes us huge headaches and I wasnt sure if those were the same things or not.

Thanks in advance.

The webui option controls whether the conntrack helper module for sip gets loaded by the kernel or not. Same thing as the old nf_sip setting, which no longer does anything.

Any ideas on why disabling the SIP Passthrough would kill the ability for my phones to pass registration info through to our SBC?

That option might be incorrectly named since it's not a passthrough option, it's a conntrack helper function. Enabling the option will tell the firmware to load the conntrack helper module, which is designed to help SIP clients communicate through NAT.

So in your case, enabling this option is actually required, since you do have SIP clients that need the helper.
