Don’t you need to do that on Ubiquiti EdgeRouter as well?

Yeah, but via the GUI or SSH, no need for telnet.

Right, I saw that. The Cmd run screen on that KB is using Windows XP and then uses a CMD of Windows 7, very confusing

Just FYI I'm using the EdgeRouter PoE v1.9.1 and when I disabled the ALG, all my phones quit working. Thank God for NTG & Scott we are back up and running but for the most part we turned ALG back on. I'm not 100% sure but it appears UBNT is the first vendor I've come across where ALG for SIP actually works. I've always used Linksys, DLink, Sonicwall etc and ALG/SIP is ALWAYS the first thing support wants you to disable.
Has anyone ran across any issues with the Edge Router yet?

I always disable it.
You said it works. But did it really? or did it not jsut not break something?
I have 20 something EdgeRouters in the wild at clints and almos tall sites have SIP phones and I have this settign off.

I use Yealink phones. For the most part, Scott made sense in that STUN servers can be hit or miss at times. There have been times I can go register a phone without STUN enabled and it works, and randomly another phone may not be able to register until I enable it.
Today, I want to say 99% of every phone today at one office has it enabled and working and registered successfully. Again I'm not a VoIP Engineer, I've only had to be a guy to deploy it back in the day when I worked in telcos. So I've deployed phones, cabling, networks and done some of the config from a customer point of view but never from the NOC side.
I have sat with the engineers 1000's of times and at that time in my life I just knew VoIP worked. However after the last 3-5 years of dealing with VoIP/PBX I come to respect it more and more but I also come to scratch my head more and more when what logically shouldn't work, works

All my systems have SIP ALG disabled and I don’t use STUn. SIP ALG needs to be disabled even for Obihai, Ooma and VOIP devices I know.

For another site I manage, I don't use stun and I also have ALG/SIP disabled on SonicWall but it is vlaned.
