So the question you should be asking yourself is why is registration failing?
Exactly. It's the only question I've been asking lately.
Re: what's reported here, I just mean that there appears to be a gap/mismatch between the HT-701 doc and the Fongo KB link. Your response confirmed that. I also suspect something related to the ATA because a SIP client on the same network/same setup works just fine.
Is your internet connectivity dropping frequently? That's an ISP issue.
Not at all -- quite the contrary. Teksavvy DSL has been rock solid -- the only downtimes I've experienced since 2012 are a few maintenance windows and a power grid related downtime (I can count them on both hands).
I have a combo TP-Link modem/router that has been quite reliable but presumably isn't the greatest option for FPL/VoIP. I hope to get a standalone router at some point when funds allow, and will make sure I pick a recommended option.
Even still, at the risk of a cliched response, I go for months at a time without registration issues and my config doesn't change (except for the last month, due to the need to troubleshoot this issue).
Are you constantly turning off your modem and router before going to sleep?
If so, when you wake up, the proper device startup order is modem-->router (wait about 5 minutes)-->ATA.
Interesting point. I do have my modem/router/ATA connected to a timer that reboots nightly at around 3 am EST. I don't have it set up such that the modem/router comes back on, and then the ATA 5 minutes afterwards. I'll have to look into setting up this behaviour with two timers.
Thanks for the link. I've seen that general info posted around, but I'll make sure I keep it handy.
