Decided to give using pjsip trunk with voip.ms another go. Unfortunately, I’m again experiencing the same intermittent registration drops that last for about 30sec. It appears to happen when the system is not in use, no matter for how short a time.

I did try @sorvani tips on his blog, both setting expiration to 120 and Max retries to 0 with no difference. Voip.ms support says they don’t see a problem on their end, that I can register and they can see traffic no problem. I can maintain a pjsip registration with Flowroute all day long with 0 issues using the exact same config/firewall/isp.
Does anyone have any suggestions on how I can dig deeper on my end on how/why the registration is dropping?
Thanks.
