DC112A - disable SIP ALG

[multa-paucis]

How to disable the SIP ALG function on the DC112A router successfully? 

I have already ticked the disable box for SIP ALG in the advanced settings.

However, the SIP ALG detector software by Visualware indicates SIP ALG is still enabled.  

Please advise

he SIP ALG feature can be be disabled simply by going to Advanced-->Setup--> WAN Setup and selecting Disable SIP ALG there is no other ways to disable it.

Hi Darren, 

Thank you for replying. 

I've already explored the solution you're recommending. However, I need the VoIP system to work on the router without conflicting with other devices and dropouts. 

Currently, I have the DC112A and the AirCard 810s working as a single unit. Even though the SIP ALG function is disabled in the DC112A, there are no options to disable the SIP ALG function on the AIRCARD 810S. I've set up a DMZ for the AirCard and IP Phone. However, I was not able to do it on the DC112A. This is because the static IP address for the VoIP phone is not a valid IP address according to the Netgear DC112A router. 

Please note that the IP phone works with the current set up. However, after 2-3 hours the AIRCARD 810S experiences a malfunction and requires a hard reset (removing the battery and putting it back in). I am not sure what I can do now. Do you have any suggestions how to successfully run a VoIP system using the DC112A and AirCard810S. 

Kind Regards
