Title: Disable SIP ALG?
Post by: caleecs on May 21, 2020, 12:58:45 PM
Per SteveInWa's recommendation I ran the Visualware's BCS test to test my ISP quality.  I was getting red on the SIP ALG gauge. Now that I have disabled it, it shows green. See the attached image. Researching that, I found lots of recommendations to disable it, but not sure how dated that information is.

I searched on this forum and found a post that is 10 years old

I have gone ahead and disabled it on my router.. I'm wondering if there is any downside to disabling it. It seems to have something to do with security.

Related question on the BCS test, if I run the Connection Assessment Test instead of the Work From Home Assessment, I get lots of critical warnings. See attached image. This is probably the wrong place to ask (maybe dslreports is better), but if anybody has any thoughts, please let me know.

Google Voice is not impacted by SIP ALG, but other VoIP services may be.  It was a bad idea to begin with, and it is rarely used, and it just causes trouble, so it's fine to leave it disabled.  There is no impact whatsoever to leaving it that way.

I am not going to continue the discussion about your ISP connection, since I've repeatedly pointed out that it is the root cause of the instability of your VoIP experience.  You can take your OBiTALK device and phone to some other location (friend's or relative's house with a different/better ISP service) to confirm or dispute this.

How can my VOIP experience be fine with Ooma if my ISP connection is the root cause of the instability of my VOIP experience?

And in that case, how will switching to Callcentric  be any better as you recommended in my other thread.

You had also specifically said that what I needed to check was that my MOS scores were over 4.0 to indicate my network service was not an issue which I have (they are averaging 4.2 incoming and outgoing).
