Lets pay attention to the comment from PeterFales - he doesn't have a router in his system but is still having the same problem. Doesn't this mean that "SIP ALG" is a red herring?
Seems to me that if the router wasn't handling things right, it wouldn't work fine for days and then disconnect. It sounds more like a problem between the Obihai site and the phonepower site.
Time is counting down for me on whether I cancel the year of phonepower or not, and we haven't really seen an answer for this. Is that because some people don't have the problem, or just don't comment on the forum?
One workaround is simply to cycle power off/on the obihai device fairly often, like every morning, but that's extremely halfassed. Shouldn't have to treat a new VOIP service like a $50 used car.
Are there router brands that don't have this problem, or - more likely - is this an obihai problem that they aren't bothering to fix? GV never did this, nor did
VOIP.MS.
Getting right down to it, the PhonePower service seems to just be unreliable with Obi devices, that seems to be the long and the short of it. The SIP ALG advice may just be baffling us with BS while the 30-day refund period runs out. Sorry if I sound cynical, but this is the "preferred provider" Obi directed us to... where are they now?
