Can't make or receive calls using GVoice since this morning

I hopped on this thread back in May 2018 reporting the same problems when GV switched from XMPP to SIP. At that time I tried all the suggested steps and still could not get RTP to flow reliably and occasionally would get the number your trying to call has not registered with SP message. I switched my Wife's phone to Callcentric and she has had flawless service since. I stayed on my old GV number and left the country till September. When I was home in September I still had RTP problems so I reset the OBI202 and problem still there, tried moving my GV number to a new account and later back, problem still there. Here we are in 2019 and I have not seen any new firmware releases from Polycomm and it seems like this GV problem is still present for some, so I am wondering what are the latest recommendations to resolve? I don't have Google Chat settings in the legacy settings of GV configuration.
My current situation: Reboot my Cisco E4200 router and then I can make phone calls on my GV # on SP1 and RTP flows fine. In general I can make calls for about 10 minutes before RTP stops flowing. I have made a call last for an hour after a reboot, but then the very next call I make no audio. Something blocks RTP after about 10 minutes but yet calls can be made outbound with no audio and I receive calls inbound with no audio. Mean while my wife's Callcentric # on SP2 works fine. My OBI202 is configured to be in my router's DMZ so it's outside the firewall. My service provider has my cable modem in bridged mode so nothing should be blocked. SIP ALG is not enabled on my router.
I'd like to get my GV working consistently again any suggestions on how to proceed? Hate to buy another router (thinking that might be the problem) as this one has worked fine for GV XMPP for 2 years and Vonage for 8 years before that.
Google Voice uses SRTP. Whatever you experienced during the XMPP days is irrelevant; the entire Google Voice infrastructure has been replaced. You don't need to use the DMZ. You have some non-OBi problem with your home network.
See today's post below your original post, and follow my instructions to the letter.

To close out my problem and hopefully help someone else I did finally resolve my problem last month and SteveInWA was spot on "it was something else in my network". My Obi202 would not consistently pass GV RTP streams but Callcentric on the same adapter worked fine. I had my Obi202 directly connected to my ISP's cable modem eliminating my WiFi router and still had the same problems.
To eliminate my network connection as the source of the problem, I took my Obi202 to two other homes in the neighborhood who use different ISP's and GV worked flawlessly for up to 2 hours. Then trying on my next door neighbors house with the same ISP (TW/Brighthouse/Spectrum) as me, same result worked flawless. Had my ISP come out a few days later to replace their Motorola SURFboard SBG6580 cable modem and boom problem solved. When I asked the tech why that cable modem would be blocking RTP occasionally for GV but not callcentric, he said he did not know why but that it was older technology and that they no longer use those SBG's.
I'm 3+ weeks on my GV number no problem, a little over a week for my wife's number who is reporting screeching white noise several times daily on inbound calls. We are monitoring to determine a common theme, so far always same inbound caller that problem occurs.
Thanks to SteveInWA and DrGeoff you guys are doing a thankless job of answering tons of idiot and not so idiot questions trying to help us all.....

Wow, that was strange. I'm glad you finally found the source of the problem. Thanks for circling back.

Wow, SBG6580 brings up (bad) memories. It has been a long long time since I dealt with a SBG6580, but they had some very interesting (i.e. complex and confusing) configuration and firewall settings. And some releases of the firmware were even less helpful than others.
And while I do understand the initial appeal to some, the general agreement from experts is that friends don't let friends purchase or use combo devices (you end up with one or more compromises).

The problem is, the large majority of consumers are not "experts", nor do all "experts" actually know what they're talking about ("male answer syndrome"), present company excluded ;).
In this particular case, the OP is simply using a very old (by tech standards) product, which ought to have been replaced already. If a consumer is renting their cable gateway, they can simply call the cable company, tell them that it's broken, and ask for a replacement, which should be a current model device.
I'm not arguing that a combo device becomes problematic if only one of its functions breaks or becomes outdated, but that, in the real world, most people's brains start hearing "yada yada yada blah blah blah" when we techies start suggesting a complex (to them) solution of two or three different devices, each with its own configurations to understand, cabling that adds more points of failure, etc. I also acknowledge that cable ISP customers may save money by buying their own equipment, as long as they understand that it will become obsolete in a few years.
I don't know about other cable ISPs, but Comcast has been very good about maintaining a list of the various DOCSIS 3.0 products they permit on their network, and they are now leasing a mesh router solution. Their non-mesh xFi gateway is a fine product, with excellent WiFi performance, and it is required for their own VoIP service. I'm not a Comcast customer, but several of my neighbors are, and I was surprised at how well their gateways work in two-story houses, and they work just fine with OBi devices.
